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. Setting
STBY to a voltage between 0.3 and 1.2 V may cause malfunction and should be avoided. 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. If the IC is switched on again while this voltage is present, overshoot may
occur on the output. 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
overall stability and transient response of the regulator, and should be set to the largest possible value for the application
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
capacitor of recommendation)
11.) About the equivalent series resistance (ESR) of a ceramic capacitor
Capacitors generally have ESR (equivalent series resistance)
and it operates stably in the ESR-IOUT area shown on the right.
Since ceramic capacitors, tantalum capacitors, electrolytic
capacitors, etc. generally have different ESR, please check
the ESR of the capacitor to be used and use it within the
stability area range shown in the right graph for evaluation
of the actual application.

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:
[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
