BUxxJA3DG-C series

General Description

Key Specifications

The BUxxJA3DG-C series are linear regulators designed

as low current consumption products for power supplies in

various automotive applications.

These products are designed for up to 6.5 V as an absolute

maximum voltage and to operate until 300 mA for the

output current with low current consumption 37 µA (Typ).

These can regulate the output with a very high accuracy,

±2 %. These regulators are therefore an ideal for any

applications requiring a low current consumption.

A logical “HIGH” at the EN pin turns on the device, and in

the other side, the devices are controlled to disable by a

logical “LOW” input to the EN pin.

In case maximum power dissipation exceeds or the ambient

temperature is higher than the Maximum Junction Temperature,

overheating causes the chip temperature (Tj) to rise. The TSD

protection circuit detects this and forces the gate of output

MOSFET(Power Tr.) to turn off in order to protect the device from

overheating. When the junction temperature decreases to low, the

output turns on automatically.

Reference Voltage

Error Amplifier

Generate the reference voltage.

The error amplifier amplifies the difference between the feedback

voltage of the output voltage and the reference voltage.

If the output current increases higher than the maximum output

current, it is limited by Over Current Protection to protect the device

from damage caused by an over current.

OCP

Over Current Protection

While this block is operating, the output voltage may decrease

because the output current is limited.

If an abnormal state is removed and the output current value returns

to normal, the output voltage also returns to normal state.

Output pin is discharged by the internal resistance (Typ: 40 Ω) when

EN = “LOW” input.

Caution 1: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit

between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is

operated over the absolute maximum ratings.

Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the

properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal resistance and power dissipation taken into

consideration by increasing board size and copper area so as not to exceed the maximum junction temperature rating.

(Note 1) Do not exceed Tjmax.

(Note 2) The start-up orders of power supply (V_IN) and the V_ENdo not influence if the voltage is within the operation power supply voltage range.

(Note 1) Minimum Input Voltage must be 1.7 V or more.

Please consider that the output voltage would be dropped (Dropout voltage ΔVd) depending on the output current.

(Note 2) If the inductance of power supply line is high, please adjust input capacitor value in order to lower the input impedance.

A lower input impedance can bring out the ideal characteristic of IC as much as possible.

It also has the effect of preventing the voltage-drop at the input line.

(Note 3) Set capacitor value which do not fall below the minimum value. This value needs to consider the temperature characteristics and DC device

characteristics.

Application and Implementation

Notice: The following information is given as a reference or hint for the application and the implementation. Therefore, it does

not guarantee its operation on a specific function, accuracy, or external components in the application. Application

should be designed with sufficient margin by enough understanding the characteristics of the external components,

e.g., capacitor, and also by appropriate verification in the actual operating conditions.

Selection of External Components

Input Pin Capacitor

If the battery is placed far from the regulator or the impedance of the input-side is high, higher capacitance is required for

the input capacitor in order to prevent the voltage-drop at the input line. The input capacitor and its capacitance should be

selected depending on the line impedance which is between the input pin and the smoothing filter circuit of the power

supply. Therefore, an appropriate capacitance value which is selected by the consideration of the input impedance is

different for each application. Generally, the capacitor with capacitance value of 0.1 µF (Min) with good high frequency

characteristic is recommended for this regulator.

In addition, to prevent regulator characteristics from getting affected by deviation or variation of the external capacitor

characteristic, all input capacitors mentioned above is recommended to have a good DC bias characteristic and a stable

temperature characteristic (approximately ±15 %, e.g., X7R and X8R), satisfying high absolute maximum voltage rating

based on EIA standard. This capacitor must be placed close to the input pin and is better to be mounted on the same board

side of the regulator.

Output Pin Capacitor

The output capacitor is mandatory for the regulator in order to realize stable operation. The output capacitor with

capacitance value ≥ 0.47 µF (Min) and ESR up to 1 Ω (Max) is required between the output pin and the GND pin.

Appropriately selected capacitance value and ESR for the output capacitor can improve the transient behavior of the

regulator and can also keep the stability with better regulation loop. The correlation of the output capacitance value and

ESR is shown in the graph Output Capacitance C_OUT, ESR Available Area on the next page. As described in the graph, this

regulator is designed to be stable with ceramic capacitors such as MLCC, with capacitance value from 0.47 µF to 47 µF,

and with ESR value in the range of approximately 0 Ω to 1 Ω. The frequency range of ESR can be generally considered as

within about 10 kHz to 100 kHz.

Note that the provided stable area of the capacitance value and ESR in the graph is obtained under a specific set of

conditions which is based on the measurement result of a single IC on our board with a resistive load. In the actual

environment, the stability is affected by wire impedance on the board, input power supply impedance, and by load

impedance. Therefore, also note that a careful evaluation with actual application, actual usage environment, and actual

conditions is necessary to confirm the actual stability of the system.

Generally, in the transient event which exceeds the gain bandwidth of regulation loop caused by the input voltage fluctuation

or by the load fluctuation, the transient response ability of the regulator depends on the capacitance value of the output

capacitor. Basically, capacitance value 0.47 µF (Min) and more for the output capacitor is recommended as shown in the

table of Output Capacitance C_OUT, ESR Available Area. It is expected that the bigger the capacitance value is the better the

transient response ability will be in high frequency. Various type of capacitors can be used for this high capacity of the

output capacitor including electrolytic capacitor, electro-conductive polymer capacitor, and tantalum capacitor. Note that

depending on the type of capacitors, the size of ESR (≤1 Ω) absolute value, temperature dependency of capacitance value,

and increasing ESR at cold temperature needs to be taken into consideration.

Similar to the input pin capacitor, to avoid the influence of the deviation and variation caused by the external capacitor

characteristic, all output capacitor mentioned above must select good DC bias characteristic and temperature characteristic

(approximately ±15 %, e.g., X7R, X8R) satisfying high absolute maximum voltage rating based on EIA standard. These

capacitors should be placed close to the output pin and mounted on the same board side of the regulator, not to be

influenced by implement impedance.

Surge Voltage Protection for Linear Regulators

The following shows some helpful tips to protect ICs from the possibility of surge being input which exceeds absolute

maximum rating.

Positive Surge to the Input

If there is any potential risk that positive surge higher than absolute maximum rating, e.g., 6.5 V, may be applied to the

input, a Zener Diode should be insert between the VIN and the GND to protect the device as shown in Figure 262.

Negative Surge to the Input

If there is any potential risk that negative surge lower than the absolute maximum rating, e.g., -0.3 V, may be applied to

the input, a Schottky Diode should be insert between the VIN and the GND to protect the device as shown in Figure 263.

Reverse Voltage Protection for Linear Regulators

A linear regulator which is one of the integrated circuits (IC) operates normally in the condition that higher input voltage is

always supplied than the output voltage. However, there is a possibility of abnormal situation to occur where the output voltage

becomes higher than the input voltage. As for the input and output, voltage and current condition may be reversed due to

reverse polarity connection and certain inductor component. If the countermeasure is not implemented, it may cause damage

to the IC. The following describe protection method of ICs in reverse voltage occasion.

Protection Against Reverse Input/Output Voltage

In the case where MOS FET is used as a pass transistor, a parasitic body diode generally exists between the drain-source.

If the output voltage becomes higher than the input voltage and with its voltage difference exceeding V_Fof the body diode,

the reverse current flows from the output to the input via body diode as shown in Figure 264.

Because this body diode is parasitic element, current which flows in it is not limited by the protection function. Therefore,

too much reverse current may cause damage to degrade or may destroy the semiconductor elements of the regulator.

Protection Against Reverse Input/Output Voltage – continued

To prevent the reverse current flow inside the IC, as an effective solution implement an external bypass diode as shown in

Figure 265. Note that the bypass diode must be turned on prior to the body diode inside the IC. Forward voltage V_Flower

than the internal body diode should be selected as external bypass diode. Should select a diode which has a rated reverse

voltage greater than the IC’s input maximum voltage and also which has a rated forward current greater than the anticipated

reverse current in the actual application.

Figure 265. Bypass Diode for Reverse Current Diversion

A Schottky barrier diode which has a characteristic of low forward voltage (V_F) matches the requirement for the external

diode to protect the IC from the reverse current, however it also has a characteristic that the leakage (I_R) caused by the

reverse voltage can be bigger than other diodes. Therefore, it should be taken into a consideration when choosing it,

because if I_Ris large, it may cause current consumption to increase, or output voltage to rise in the light-load current

condition. I_Rof Schottky diode has positive temperature characteristic, which the details should be checked by the

datasheet of the product, and careful confirmation of the behavior in the actual application is mandatory.

Even in the condition where the input/output voltage is inverted, if the VIN pin becomes open as shown in Figure 266, or

if the VIN pin becomes high impedance as designed in the system, it cannot damage or degrade the parasitic element. It

is because a reverse current via pass transistor becomes extremely low. In this case, therefore, the protection external

diode is not necessary.

Protection Against Input Reverse Voltage

When connecting input of IC to power supply, if accidentally reverse connect the plus and minus or if input may become

lower than the GND pin, large current which flows in the internal electrostatic breakdown prevention diode set between

VIN and GND as shown in Figure 267 may destroy the IC.

Simplest way to prevent this problem is to connect Schottky barrier diode or rectifier diode to power supply line in series

as shown in Figure 268. However, it increases a power loss calculated as V_F× I_IN, and due to forward voltage V_Fof diode

the voltage drop occurs to input voltage at the normal power supply line.

Generally, the Schottky barrier diode has lower V_Fthan rectifier diode and contributes to rather smaller power loss. If IC

has load currents, the required input current to the IC is also bigger. In this case, this external diode generates heat more,

therefore it should be taken into the consideration of a selection for diode with enough margin in power dissipation. On the

other hands, in the reverse connection condition, a reverse current passes this diode, however, it can be negligible because

its small amount.

Protection Against Input Reverse Voltage - continued

Figure 269 shows a circuit in which a P-channel MOSFET is connected in series to the power. The body diode (parasitic

element) is located in the drain-source junction area of the MOSFET. The drop voltage in a forward connection is calculated

by the on-state resistance of the MOSFET and the output current I_O. Because it is smaller than the drop voltage by the

diode as shown in Figure 268, as a result power loss becomes less. No current flows in a reverse connection where the

MOSFET remains off in Figure 269.

If the gate-source voltage exceeds maximum rating of MOSFET gate-source junction with considered derating curve,

reduce the gate-source junction voltage by connecting resistor voltage divider as shown in Figure 270.

Protection Against Reverse Output Voltage when Output Connect to an Inductor

If the output load is inductive, electrical energy accumulated in the inductive load is released to the ground at the moment

that the output voltage is turned off. There is an ESD protection diode between output and ground pin inside the IC and

large current flowing in this diode may eventually destruct the IC. To prevent this situation, connect a Schottky barrier diode

in parallel to the diode as shown in Figure 271.

Further, if a long wire is used to connect the output pin of the IC and the load, observe the waveform on an oscilloscope to

confirm whether the negative voltage is generated at the VOUT pin or not when the output voltage is turned off, since there

is a possibility of the load to become inductive. An additional diode is required for a motor load that is affected by its counter

electromotive force, as it produces an electrical current in a similar way.

Thermal Design

This product exposes a frame on the back side of the package for thermal efficiency improvement. The power consumption

of the IC is decided by the dropout voltage condition, the load current and the current consumption. Refer to power dissipation

curves illustrated in Figure 12 when using the IC in an environment of Ta ≥ 25 °C. Even if the ambient temperature Ta is at

25°C, chip junction temperature (Tj) can be very high depending on the input voltage and the load current. Consider the

design to be Tj ≤ Tjmax = 150 °C in whole operating temperature range.

Should by any condition the maximum junction temperature Tjmax = 150 °C rating be exceeded by the temperature increase

of the chip, it may result in deterioration of the properties of the chip. The thermal impedance in this specification is based on

recommended PCB and measurement condition by JEDEC standard. Therefore, need to be careful because it might be

different from the actual use condition. Verify the application and allow sufficient margins in the thermal design by the following

method to calculate the junction temperature Tj. Tj can be calculated by either of the two following methods.

1. The following method is used to calculate the junction temperature Tj with ambient temperature Ta.

푇푗 = 푇푎 + 푃_퐶× 휃_퐽퐴[°C]

Where:

Tj

is the Junction Temperature

Ta is the Ambient Temperature

is the Power Consumption

P_C

θ_JAis the Thermal Resistance (Junction to Ambient)

2. The following method is also used to calculate the junction temperature Tj with top center of case’s (mold) temperature T_T.

푇푗 = 푇_ꢀ+ 푃_퐶× 훹 [°C]

퐽ꢀ

Where:

Tj

T_T

P_C

is the Junction Temperature

is the Top Center of Case’s (mold) Temperature

is the Power consumption

Ψ_JTis the Thermal Resistance (Junction to Top Center of Case)

3. The following method is used to calculate the power consumption Pc (W).

푃푐 = (푉 − 푉_푂푈ꢀ) × ꢁ_푂푈ꢀ+ 푉 × ꢁ_퐶퐶[W]

퐼푁

Where:

P_C

is the Power Consumption

V_INis the Input Voltage

V_OUTis the Output Voltage

I_OUTis the Load Current

I_CCis the Current Consumption

Calculation Example

If V_IN= 5.0 V, V_OUT= 3.3 V, I_OUT= 100 mA, I_CC= 37 μA, the power consumption Pc can be calculated as follows:

푃_퐶= (푉 − 푉_푂푈ꢀ) × ꢁ_푂푈ꢀ+ 푉 × ꢁ_퐶퐶

퐼푁

(

)

5.0 푉 – 3.3 푉 × 100 푚ꢂ + 5.0 푉 × 37 휇ꢂ

=

= 0.17 푊

At ambient temperature Ta = 125 °C,

the thermal impedance (Junction to Ambient) θ_JA= 135.7 °C/W (4-layer PCB)

푇푗 = 푇푎푚푎푥 + 푃_퐶× 휃_퐽퐴

= 125 °ꢃ + 0.17 푊 × 135.7 °ꢃ/푊

= 148.1 °ꢃ

When operating the IC, the top center of case’s (mold) temperature T_T= 100 °C, Ψ_JT= 27 °C/W (4-layer PCB)

푇푗 = 푇_ꢀ+ 푃_퐶× 훹

퐽ꢀ

= 100 °ꢃ + 0.17 푊 × 27 °ꢃ/푊

= 104.6 °ꢃ

If it is difficult to ensure the margin by the calculations above, it is recommended to expand the copper foil area of the

board, increasing the layer and thermal via between thermal land pad for optimum thermal performance.

Operational Notes

1.

2.

Reverse Connection of Power Supply

Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when

connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply

pins.

Power Supply Lines

Design the PCB layout pattern to provide low impedance supply lines. Furthermore, connect a capacitor to ground at

all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic

capacitors.

3.

4.

Ground Voltage

Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.

Ground Wiring Pattern

When using both small-signal and large-current ground traces, the two ground traces should be routed separately but

connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal

ground caused by large currents. Also ensure that the ground traces of external components do not cause variations

on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance.

5.

6.

Operating Conditions

The function and operation of the IC are guaranteed within the range specified by the recommended operating

conditions. The characteristic values are guaranteed only under the conditions of each item specified by the electrical

characteristics.

Inrush Current

When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow

instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply.

Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing

of connections.

7.

Thermal Consideration

The power dissipation under actual operating conditions should be taken into consideration and a sufficient margin

should be allowed in the thermal design. On the reverse side of the package this product has an exposed heat pad for

improving the heat dissipation. The amount of heat generation depends on the voltage difference between the input

and output, load current, and bias current. Therefore, when actually using the chip, ensure that the generated heat

does not exceed the Pd rating. If Junction temperature is over Tjmax (= 150 °C), IC characteristics may be worse due

to rising chip temperature. Heat resistance in specification is measurement under PCB condition and environment

recommended in JEDEC. Ensure that heat resistance in specification is different from actual environment.

8.

9.

Testing on Application Boards

When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject

the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should

always be turned off completely before connecting or removing it from the test setup during the inspection process. To

prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and

storage.

Inter-pin Short and Mounting Errors

Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in

damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin.

Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and

unintentional solder bridge deposited in between pins during assembly to name a few.

10. Unused Input Pins

Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and

extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small charge

acquired in this way is enough to produce a significant effect on the conduction through the transistor and cause

unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the power

supply or ground line.

Operational Notes – continued

11. Regarding the Input Pin of the IC

In the construction of this IC, P-N junctions are inevitably formed creating parasitic diodes or transistors. The

operation of these parasitic elements can result in mutual interference among circuits, operational faults, or physical

damage. Therefore, conditions which cause these parasitic elements to operate, such as applying a voltage to an

input pin lower than the ground voltage should be avoided. Furthermore, do not apply a voltage to the input pins

when no power supply voltage is applied to the IC. Even if the power supply voltage is applied, make sure that the

input pins have voltages within the values specified in the electrical characteristics of this IC.

12. Ceramic Capacitor

When using a ceramic capacitor, determine a capacitance value considering the change of capacitance with

temperature and the decrease in nominal capacitance due to DC bias and others.

13. Thermal Shutdown Protection Circuit (TSD)

This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always

be within the IC’s maximum junction temperature rating. If however the rating is exceeded for a continued period, the

junction temperature (Tj) will rise which will activate the TSD circuit that will turn OFF power output pins. When the Tj

falls below the TSD threshold, the circuits are automatically restored to normal operation.

Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no

circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat

damage.

14. Over Current Protection Circuit (OCP)

This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This

protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should

not be used in applications characterized by continuous operation or transitioning of the protection circuit.

15. Enable Pin

The EN pin is for controlling ON/OFF the output voltage. Do not make voltage level of chip enable keep floating level,

or between V_ENHand V_ENL. Otherwise, the output voltage would be unstable or indefinite.
