Internal Power Supply
Power supply for internal circuit.
In case maximum power dissipation exceeds or when the junction
temperature rises and the chip temperature (Tj) exceeds the heating
protection set temperature. The TSD protection circuit detects this
and forces the gate of output MOSFET to turn off in order to protect
the device from overheating. (Typ: 175 °C) When the junction
temperature decreases to low, the thermal Shutdown protection is
released and the output turns on automatically.

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 5) If the inductance of power supply line is high, 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 6) Set capacitor value which do not fall below the minimum value. This value needs to consider the temperature characteristics and DC bias
characteristics.
(Note 7) It is recommended to use ceramic capacitors that have low ESR characteristics for the phase compensation.
In case of using electrolytic capacitor or ceramic capacitor with large ESR (> 100 mΩ), note that ceramic capacitor with 1 μF and more must be
connected near VOUT pin in parallel.

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 the specific function, accuracy or external components in the application. In the
application, it shall be designed with sufficient margin by enough understanding about 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
In order to fully demonstrate the performance of this IC, it is recommended that the input capacitor be placed as close as
possible to the input pin and the GND pin without being affected by mounting impedance, etc., and that it be laid out on the
same mounting surface. In this case, a capacitor with a capacitance value of 0.1 μF (Min) or higher is recommended.
Depending on the layout of the peripheral components, including this IC, from the input power supply, if the distance from
the input power supply is too far or the impedance of the input side is too high, for example, the current supply due to the
load response of the IC cannot be withstood, and the output voltage may become unstable due to fluctuations in the input
voltage. In such a case, it is necessary to use a large capacitor to prevent the input voltage from dropping. Select the
capacitance of the input pin capacitor according to the line impedance between the power smoothing circuit and the input
pin, and the load response required by the application.
In addition, the consideration should be taken as the input pin capacitor, to prevent an influence to the regulator’s
characteristic from the deviation or the variation of the input capacitor’s characteristic. All input capacitors mentioned above
are recommended to have a good DC bias characteristic and a temperature characteristic (approximately ±15 %, e.g. X7R,
X8R) with being satisfied high absolute maximum voltage rating based on EIA standard.
Output Pin Capacitor
The output capacitor is mandatory for the regulator in order to realize stable operation. The output capacitor with
capacitance value of 1 μF (Min) or higher and ESR up to 100 mΩ (Max) must be required between the output pin and the
GND pin.
A proper selection of appropriate both the 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 on the next page as the output capacitor’s capacitance value and the stability
region for ESR. As described in this graph, this regulator is designed to be stable with ceramic capacitors as of MLCC,
with the capacitance value from 1 μF to 500 μF and with ESR value within almost 0 Ω to 100 mΩ. The frequency range of
ESR can be generally considered at around 1 MHz.
Note that the provided the 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 in 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 also loads
impedance. Therefore, note that a careful evaluation of the actual application, the actual usage environment and the actual
conditions should be done to confirm the actual stability of the system.
Generally, in the transient event which is caused by the input voltage fluctuation or the load fluctuation beyond the gain
bandwidth of the regulation loop, the transient response ability of the regulator depends on the capacitance value of the
output capacitor. Basically the capacitance value of 1 μF (Min) or higher for the output capacitor is recommended as shown
in the table on Output Capacitance COUT, ESR Available Area. Using bigger capacitance value can be expected to
improve better the transient response ability in a high frequency. Various types of capacitors can be used for the output
capacitor with high capacity which includes electrolytic capacitor, electro-conductive polymer capacitor and tantalum
capacitor. Noted that, depending on the type of capacitors, its characteristics such as ESR (≤ 100 mΩ) absolute value
range, a temperature dependency of capacitance value and increased ESR at cold temperature needs to be taken into
consideration. When using capacitor with large ESR (≤ 100 mΩ) , note that ceramic capacitor with 1 µF or higher must be
connected in parallel to keep stability. In this case, the total capacitance should be less than 500 µF.
In addition, the same consideration should be taken as the input pin capacitor, to prevent an influence to the regulator’s
characteristic from the deviation or the variation of the external capacitor’s characteristic. All output capacitors mentioned
above are recommended to have a good DC bias characteristic and a temperature characteristic (approximately ±15 %,
e.g. X7R, X8R) with being satisfied 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 possible inputting surge voltage which exceeds absolute
maximum ratings.
Positive Surge to the Input
If there is any potential risk that positive surges higher than absolute maximum ratings, it is applied to the input, a
Zener Diode should be inserted between the VIN pin and the GND to protect the device as shown in Figure 56.

Reverse Voltage Protection for Linear Regulators
A linear regulator which is one of the integrated circuit (IC) operates normally in the condition that the input voltage is
higher than the output voltage. However, it is possible to happen the abnormal situation in specific conditions which is
the output voltage becomes higher than the input voltage. A reverse polarity connection between the input and the output
might be occurred or a certain inductor component can also cause a polarity reverse conditions. If the countermeasure
is not implemented, it may cause damage to the IC. The following shows some helpful tips to protect ICs from the reverse
voltage occasion.
Protection against Reverse Input/Output Voltage
In the case that MOSFET is used for the pass transistor, a parasitic body diode between the drain-source generally
exists. If the output voltage becomes higher than the input voltage and if its voltage difference exceeds VF of the body
diode, a reverse current flows from the output to the input through the body diode as shown in Figure 58. The current
flows in the parasitic body diode is not limited in the protection circuit because it is the parasitic element, therefore
too much reverse current may cause damage to degrade or destroy the semiconductor elements of the regulator.

Protection against Reverse Input/Output Voltage – continued
An effective solution for this problem is to implement an external bypass diode in order to prevent the reverse current
flow inside the IC as shown in Figure 59. Especially in applications where the output voltage setting is high and a
large output capacitor is connected, be sure to consider countermeasures for large reverse current values. Note that
the bypass diode must be turned on prior to the internal body diode of the IC. This external bypass diode should be
chosen as being lower forward voltage VF than the internal body diode. It should to be selected 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 59. Bypass Diode for Reverse Current Diversion
A Schottky Barrier Diode which has a characteristic of low forward voltage (VF) can meet to the requirement for the
external diode to protect the IC from the reverse current. However, it also has a characteristic that the leakage (IR)
caused by the reverse voltage is bigger than other diodes. Therefore, it should be taken into the consideration to
choose it because if IR is large, it may cause increase of the current consumption, or raise of the output voltage in the
light-load current condition. IR characteristic of Schottky Diode has positive temperature characteristic, which the
details shall be checked with the datasheet of the products, and the careful confirmation of behavior in the actual
application is mandatory.
Even in the condition when the input/output voltage is inverted, if the VIN pin is open as shown in Figure 60, or if the
VIN pin becomes high-impedance condition as designed in the system, it cannot damage or degrade the parasitic
element. It's because a reverse current via the pass transistor becomes extremely low. In this case, therefore, the
protection external diode is not necessary.

Protection against Input Reverse Voltage
When the input of the IC is connected to the power supply, accidentally if plus and minus are routed in reverse, or if
there is a possibility that the input may become lower than the GND pin, it may cause to destroy the IC because a
large current passes via the internal electrostatic breakdown prevention diode between the VIN pin and the GND
pin inside the IC as shown in Figure 61.
The simplest solution to avoid this problem is to connect a Schottky Barrier Diode or a rectifier diode in series to the
power supply line as shown in Figure 62. However, it increases a power loss calculated as VF x ICC, and it also causes
the voltage drop by a forward voltage VF at the supply voltage while normal operation.
Generally, since the Schottky Barrier Diode has lower VF, so it contributes to rather smaller power loss than rectifier
diodes. 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 select a diode with enough margin in power dissipation. On the other hand, a reverse
current passes this diode in the reverse connection condition, however, it is negligible because its small amount.

Figure 63 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 from the on state resistance of the MOSFET and the output current IOUT. It is smaller than the drop voltage
by the diode as shown in Figure 62 and results in less of a power loss. No current flows in a reverse connection where
the MOSFET remains off in Figure 63.
If the gate-source voltage exceeds maximum rating of MOSFET gate-source junction with derating curve in
consideration, reduce the gate-source junction voltage by connecting resistor voltage divider as shown in Figure 64.

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. IC integrates ESD protection diodes between the IC output and ground
pins. A large current may flow in such condition finally resulting on destruction of the IC. To prevent this situation,
connect a Schottky Barrier Diode in parallel to the integrated diodes as shown in Figure 65.
Further, if a long wire is in use for the connection between the output pin of the IC and the load, confirm that the
negative voltage is not generated at the VOUT pin when the output voltage is turned off by observation of the
waveform on an oscilloscope, since it is possible that the load becomes 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 66 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.

Calculation Example (HTSOP-J8)
If VIN = 13.5 V, VOUT = 5.0 V, IOUT = 200 mA, ICC = 170 μA, the power consumption Pc can be calculated as follows:
푃ꢀ = (푉 − 푉ꢃꢄꢅ) × 퐼ꢃꢄꢅ + 푉 × 퐼ꢀꢀ
ꢁꢂ
ꢁꢂ
(
)
= 13.5 푉 – 5.0 푉 × 200 푚퐴 + 13.5 푉 × 170 휇퐴
= 1.7 푊
At the maximum ambient temperature Tamax = 85 °C,
the thermal impedance (Junction to Ambient) θJA = 26.0 °C/W (4-layer PCB)
푇푗 = 푇푎푚푎푥 + 푃ꢀ × 휃ꢆꢇ
= 85 °퐶 + 1.7 푊 × 26.0 °퐶/푊
= 129.2 °퐶
When operating the IC, the top center of case’s (mold) temperature TT = 100 °C,
the Thermal Resistance (Junction to Top Center of Case) ΨJT = 10 °C/W (1-layer PCB)
푇푗 = 푇ꢅ + 푃ꢀ × 훹
ꢆꢅ
= 100 °퐶 + 1.7 푊 × 10 °퐶/푊
= 117.0 °퐶
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
This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them
isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a
parasitic diode or transistor. For example, (refer to figure below):
When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.
When GND > Pin B, the P-N junction operates as a parasitic transistor.
Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual
interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be
avoided.

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. Functional Safety
