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 Pd.
(Note 2) Applicable for product with Enable Input.
The start-up orders of power supply (VCC) and the CTL pin do not influence if the voltage is within the operation power supply voltage range.

Selection of Components Externally Connected
VCC
Insert capacitors with a capacitance of 0.1 μF or higher between the VCC and the GND. Choose the capacitance
according to the line between the power smoothing circuit and the VCC. Selection of the capacitance also depends
on the application. Verify the application and allow sufficient margins in the design. We recommend using a capacitor
with excellent voltage and temperature characteristics.
Output Pin Capacitor
In order to prevent oscillation, a capacitor needs to be placed between the output pin and GND. We recommend using
a capacitor with a capacitance of 10 μF (Typ) or higher. Electrolytic, tantalum and ceramic capacitors can be used.
When selecting the capacitor ensure that the capacitance of 6 μF or higher is maintained at the intended applied
voltage and temperature range. Due to changes in temperature the capacitor’s capacitance can fluctuate possibly
resulting in oscillation. For selection of the capacitor refer to the data of Figure 40.
The stable operation range given in the data of Figure 40 and Figure 41 is based on the standalone IC and resistive
load. For actual applications the stable operating range is influenced by the PCB impedance, input supply impedance
and load impedance. Therefore verification of the final operating environment is needed.
When selecting a ceramic type capacitor, we recommend using X5R, X7R or better with excellent temperature and
DC-biasing characteristics and high voltage tolerance.
Also, in case of rapidly fluctuation of input voltage and load current, select the capacitance in accordance with verifying
that the actual application meets with the required specification. Mount the capacitor as much as possible near
connected pin.

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 VCC pin and the GND to protect the device as shown in Figure 43.

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. In this case, use a capacitor with a capacitance with less than 1000
μF, to reduce damage to internal circuits or elements. 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 45. 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 46. 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 rating voltage and also which has a rated forward current greater than the anticipated
reverse current in the actual application.

Figure 46. 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 VCC pin is open as shown in Figure 47, 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 input pin and the GND pin inside the IC as
shown in Figure 48.
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 49. However, it 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 50 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 IO. It is smaller than the drop voltage by
the diode as shown in Figure 49 and results in less of a power loss. No current flows in a reverse connection where the
MOSFET remains off in Figure 50.
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 51.

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 52.
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.
Within this IC, the power consumption is decided by the dropout voltage condition, the load current and the circuit current.
Refer to power dissipation curves illustrated in Figure 53, 54 when using the IC in an environment of Ta ≥ 25 °C. Even if the
ambient temperature Ta is at 25 °C, depending on the input voltage and the load current, chip junction temperature can be
very high. Consider the design to be Tj ≤ Tjmax = 150 °C in all possible 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. Verify the application and allow sufficient margins in
the thermal design by the following method is used to calculate the junction temperature Tj.
Tj can be calculated by either of the two following methods.

Operational Notes
1. 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.
2. 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. Ground Voltage
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.
4. 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. Operating Conditions
The function and operation of the IC are guaranteed within the range specified by the operating conditions. The
characteristic values are guaranteed only under the conditions of each item specified by the electrical characteristics.
6. 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. 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.
8. 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.

9. 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.

10. 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.
11. Thermal Shutdown 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.
12. 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.
13. 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.
14. CTL Pin
The CTL pin is for controlling ON/OFF the output voltage. Do not make voltage level of chip enable keep floating
level, or between VthH and VthL. Otherwise, the output voltage would be unstable or indefinite.
15. Functional Safety
“ISO 26262 process compliant to support ASIL-*”
A product that has been developed based on an ISO 26262 design process compliant to the ASIL level described in
the datasheet.
“Safety mechanism is implemented to support functional safety (ASIL-*)”

2. ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate
safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which
a failure or malfunction of our Products may cause. The following are examples of safety measures:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3. Our Products are not designed under any special or extraordinary environments or conditions, as exemplified below.
Accordingly, ROHM shall not be in any way responsible or liable for any damages, expenses or losses arising from the
use of any ROHM’s Products under any special or extraordinary environments or conditions. If you intend to use our
Products under any special or extraordinary environments or conditions (as exemplified below), your independent
verification and confirmation of product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,
H2S, NH3, SO2, and NO2
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items
[f] Sealing or coating our Products with resin or other coating materials
[g] Use of our Products without cleaning residue of flux (Exclude cases where no-clean type fluxes is used.
However, recommend sufficiently about the residue.); or Washing our Products by using water or water-soluble
cleaning agents for cleaning residue after soldering
[h] Use of the Products in places subject to dew condensation
4. The Products are not subject to radiation-proof design.
5. Please verify and confirm characteristics of the final or mounted products in using the Products.
6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse, is applied,
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect
product performance and reliability.
7. De-rate Power Dissipation depending on ambient temperature. When used in sealed area, confirm that it is the use in
the range that does not exceed the maximum junction temperature.
8. Confirm that operation temperature is within the specified range described in the product specification.
9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in
this document.
Precaution for Mounting / Circuit board design
1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product
performance and reliability.
2. In principle, the reflow soldering method must be used on a surface-mount products, the flow soldering method must
be used on a through hole mount products. If the flow soldering method is preferred on a surface-mount products,
please consult with the ROHM representative in advance.
For details, please refer to ROHM Mounting specification

Precaution for Electrostatic
This Product is electrostatic sensitive product, which may be damaged due to electrostatic discharge. Please take proper
caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be
applied to Products. Please take special care under dry condition (e.g. Grounding of human body / equipment / solder iron,
isolation from charged objects, setting of Ionizer, friction prevention and temperature / humidity control).
Precaution for Storage / Transportation
1. Product performance and soldered connections may deteriorate if the Products are stored in the places where:
[a] the Products are exposed to sea winds or corrosive gases, including Cl2, H2S, NH3, SO2, and NO2
[b] the temperature or humidity exceeds those recommended by ROHM
[c] the Products are exposed to direct sunshine or condensation
[d] the Products are exposed to high Electrostatic
2. Even under ROHM recommended storage condition, solderability of products out of recommended storage time period
may be degraded. It is strongly recommended to confirm solderability before using Products of which storage time is
exceeding the recommended storage time period.
3. Store / transport cartons in the correct direction, which is indicated on a carton with a symbol. Otherwise bent leads
may occur due to excessive stress applied when dropping of a carton.
4. Use Products within the specified time after opening a humidity barrier bag. Baking is required before using Products of
which storage time is exceeding the recommended storage time period.
