z About power dissipation (Pd)
As for power dissipation, an approximate estimate of the heat reduction characteristics and internal power consumption of
IC are shown, so please use these for reference. Since power dissipation changes substantially depending on the
implementation conditions (board size, board thickness, metal wiring rate, number of layers and through holes, etc.), it is
recommended to measure Pd on a set board. Exceeding the power dissipation of IC may lead to deterioration of the
original IC performance, such as causing operation of the thermal shutdown circuit or reduction in current capability.
Therefore, be sure to prepare sufficient margin within power dissipation for usage.
Calculation of the maximum internal power consumption of IC (PMAX)
PMAX=(VIN-VOUT)×IOUT(MAX.) (VIN: Input voltage VOUT: Output voltage IOUT(MAX): Maximum output current)

●Operation Notes
1.) Absolute maximum ratings
Use of the IC in excess of absolute maximum ratings (such as the input voltage or operating temperature range) may result in
damage to the IC. Assumptions should not be made regarding the state of the IC (e.g., short mode or open mode) when such damage
is suffered. If operational values are expected to exceed the maximum ratings for the device, consider adding protective circuitry
(such as fuses) to eliminate the risk of damaging the IC.
2.) GND potential
The potential of the GND pin must be the minimum potential in the system in all operating conditions.
Never connect a potential lower than GND to any pin, even if only transiently.
3.) Thermal design
Use a thermal design that allows for a sufficient margin for that package power dissipation rating (Pd) under actual operating
conditions.
4.) Inter-pin shorts and mounting errors
Use caution when orienting and positioning the IC for mounting on printed circuit boards. Improper mounting or
shorts between pins may result in damage to the IC.
5.) Operation in strong electromagnetic fields
Strong electromagnetic fields may cause the IC to malfunction. Caution should be exercised in applications where strong
electromagnetic fields may be present.
6.) Common impedance
Wiring traces should be as short and wide as possible to minimize common impedance. Bypass capacitors should
be use to keep ripple to a minimum.
7.) Voltage of STBY pin
To enable standby mode for all channels, set the STBY pin to 0.3 V or less, and for normal operation, to 1.2 V or more.
STBY to a voltage between 0.3 and 1.2 V may cause malfunction and should be avoided.
Setting
Keep transition time between high and
low (or vice versa) to a minimum.
Additionally, if STBY is shorted to VIN, the IC will switch to standby mode and disable the output discharge circuit, causing
a temporary voltage to remain on the output pin.
occur on the output.
If the IC is switched on again while this voltage is present, overshoot may
Therefore, in applications where these pins are shorted, the output should always be completely discharged
before turning the IC on.
8.) Over-current protection circuit (OCP)
This IC features an integrated over-current and short-protection circuitry on the output to prevent destruction of the IC when
the output is shorted.
The OCP circuitry is designed only to protect the IC from irregular conditions (such as motor output
shorts) and is not designed to be used as an active security device for the application.
Therefore, applications should not
be designed under the assumption that this circuitry will engage.
9.) Thermal shutdown circuit (TSD)
This IC also features a thermal shutdown circuit that is designed to turn the output off when the junction temperature of the
IC exceeds about 150℃.
This feature is intended to protect the IC only in the event of thermal overload and is not designed
to guarantee operation or act as an active security device for the application.
Therefore, applications should not be designed
under the assumption that this circuitry will engage.
10.) Input/output capacitor
Capacitors must be connected between the input/output pins and GND for stable operation, and should be physically mounted as
close to the IC pins as possible. The input capacitor helps to counteract increases in power supply impedance, and increases
stability in applications with long or winding power supply traces.
The output capacitance value is directly related to the

to increase these characteristics. During design, keep in mind that in general, ceramic capacitors have a wide range of tolerances,
temperature coefficients and DC bias characteristics, and that their capacitance values tend to decrease over time. Confirm
these details before choosing appropriate capacitors for your application.(Please refer the technical note, regarding ceramic

Notice
Precaution on using ROHM Products
1.
Our Products are designed and manufactured for application in ordinary electronic equipments (such as AV equipment,
OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you
(Note 1)
, transport
intend to use our Products in devices requiring extremely high reliability (such as medical equipment
equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment including car
accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life, bodily injury or
serious damage to property (“Specific Applications”), please consult with the ROHM sales representative in advance.
Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any
damages, expenses or losses incurred by you or third parties arising from the use of any ROHM’s Products for Specific
Applications.

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 designed and manufactured for use under standard conditions and not 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:

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.
