●Power dissipation (Pd)
1. Power dissipation (Pd)
Power dissipation calculations include estimates of power dissipation characteristics and internal IC power consumption,
and should be treated as guidelines. In the event that the IC is used in an environment where this power dissipation is
exceeded, the attendant rise in the junction temperature will trigger the thermal shutdown circuit, reducing the current
capacity and otherwise degrading the IC's design performance. Allow for sufficient margins so that this power dissipation is
not exceeded during IC operation.
Calculating the maximum internal IC power consumption (PMAX)
PMAX = (VIN − VOUT) IOUT (MAX.)
VIN : Input voltage
VOUT : Output voltage
IOUT (MAX): Max. output current

*Circuit design should allow a sufficient margin for the temperature range so that PMAX < Pd.
●Input Output capacitors
It is recommended to insert bypass capacitors between input and GND pins, positioning them as close to the pins as
possible. These capacitors will be used when the power supply impedance increases or when long wiring paths are used, so
they should be checked once the IC has been mounted.
Ceramic capacitors generally have temperature and DC bias characteristics. When selecting ceramic capacitors, use X5R or
X7R, or better models that offer good temperature and DC bias characteristics and high tolerant voltages.

●Output capacitors
Mounting input capacitor between input pin and GND(as close to pin as possible), and also output capacitor between output
pin and GND(as close to pin as possible) is recommended. The input capacitor reduces the output impedance of the voltage
supply source connected to the VCC. The higher value the output capacitor goes, the more stable the whole operation
becomes. This leads to high load transient response. Please confirm the whole operation on actual application board.
Generally, ceramic capacitor has wide range of tolerance, temperature coefficient, and DC bias characteristic. And also its
value goes lower as time progresses. Please choose ceramic capacitors after obtaining more detailed data by asking
capacitor makers.

●Operation Notes
1. Absolute maximum ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc.,
can break down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit.
If any over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices,
such as fuses.
2. Thermal design
Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating
conditions.
3. Inter-pin shorts and mounting errors
Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any
connection error or if pins are shorted together.
4. Thermal shutdown circuit (TSD)
The IC incorporates a built-in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit is designed only to
shut the IC off to prevent runaway thermal operation. It is not designed to protect the IC or guarantee its operation. Do
not continue to use the IC after operating this circuit or use the IC in an environment where the operation of this circuit is
assumed.
5. Overcurrent protection circuit
The IC incorporates a built-in overcurrent protection circuit that operates according to the output current capacity. This
circuit serves to protect the IC from damage when the load is shorted. The protection circuit is designed to limit current
flow by not latching in the event of a large and instantaneous current flow originating from a large capacitor or other
component. These protection circuits are effective in preventing damage due to sudden and unexpected accidents.
However, the IC should not be used in applications characterized by the continuous operation or transitioning of the
protection circuits. At the time of thermal designing, keep in mind that the current capability has negative characteristics
to temperatures.
6. Action in strong electromagnetic field
Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to
malfunction.
7. Ground wiring pattern
When using both small signal and large current GND patterns, it is recommended to isolate the two ground patterns,
placing a single ground point at the ground potential of application so that the pattern wiring resistance and voltage
variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to change
the GND wiring pattern of any external components, either.

8. GND voltage
The potential of GND pin must be minimum potential in all operating conditions.
9. Back Current
In applications where the IC may be exposed to back current flow, it is recommended to create a path to dissipate this
current by inserting a bypass diode between the VIN and VOUT pins.

STBY

Fig. 31 Example Bypass Diode Connection
10. Testing on application boards
When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to
stress. Always discharge capacitors after each process or step. Always turn the IC's power supply off before connecting
it to or removing it from a jig or fixture during the inspection process. Ground the IC during assembly steps as an
antistatic measure. Use similar precaution when transporting or storing the IC.
11. Regarding 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 these P layers with the N layers of other elements, creating a
parasitic diode or transistor. For example, the relation between each potential is as follows:
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 can occur inevitable in the structure of the IC. The operation of parasitic diodes can result in mutual
interference among circuits, operational faults, or physical damage. Accordingly, methods by which parasitic diodes
operate, such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin, should not be used.

ambient 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

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:

[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.
