Input/Output Capacitor  
Capacity value of ceramic capacitor - DC bias characteristics  
(Example)  
It is recommended that an input capacitor is placed near pins  
between the VCC pin and GND as well as an output capacitor  
between the output pin and GND. The input is valid when the  
power supply impedance is high or when the PCB trace has  
significant length. For the output capacitor, the greater the  
capacitance, the more stable the output will be depending on  
the load and line voltage variations. However, please check the  
actual functionality of this capacitor by mounting it on a board  
for the actual application. Ceramic capacitors usually have  
different, thermal and equivalent series resistance  
characteristics, and may degrade gradually over continued  
use.

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.

Power Dissipation (Pd)  
As for power dissipation, an estimate of 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 the operation of the thermal shutdown circuit or reduction in current capability. Therefore, be sure to prepare  
sufficient margin within power dissipation for usage.

Operational Notes  
1) Absolute maximum ratings  
This product is produced with strict quality control, however it may be destroyed if operated beyond its absolute  
maximum ratings. In addition, it is impossible to predict all destructive situations such as short-circuit modes, open  
circuit modes, etc. Therefore, it is important to consider circuit protection measures, like adding a  
fuse, in case the IC is operated in a special mode exceeding the absolute maximum ratings.  
2) GND Potential  
GND potential must be the lowest potential of all pins of the IC at all operating conditions. Ensure that no pins are at a  
voltage below the ground pin at any time, even during transient condition.  
3) Setting of Heat  
Carry out the heat design that have adequate margin considering Pd of actual working states.  
4) Pin Short and Mistake Fitting  
When mounting the IC on the PCB, pay attention to the orientation of the IC. If there is mistake in the placement, the IC  
may be burned up.  
5) Actions in Strong Magnetic Field  
Using the IC within a strong magnetic field may cause the IC to malfunction.  
6) Mutual Impedance  
Use short and wide wiring tracks for the power supply and ground to keep the mutual impedance as small as possible.  
Use a capacitor to keep ripple to a minimum.  
7) STBY Pin Voltage  
To enable standby mode for all channels, set the STBY pin to 0.5 V or less, and for normal operation, to 1.1 V or more.  
Setting STBY to a voltage between 0.5 and 1.1 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  
Over current and short circuit protection is built-in at the output, and IC destruction is prevented at the time of load short  
circuit. These protection circuits are effective in the destructive prevention by sudden accidents, please avoid  
applications to where the over current protection circuit operates continuously.  
9) Thermal Shutdown  
This IC has Thermal Shutdown Circuit (TSD Circuit). When the temperature of IC Chip is higher than 175, the output  
is turned off by TSD Circuit. TSD Circuit is only designed for protecting IC from thermal over load. Therefore it is not  
recommended that you design application where TSD will work in normal condition.  
10) Actions under Strong light  
A strong light like a halogen lamp may be caused malfunction. In our testing, fluorescence light and white LED causes  
little effects for the IC, but infrared light causes strong effects on the IC. The IC should be shielded from light like  
sunrays or halogen lamps.  
11) Output capacitor  
To prevent oscillation at output, it is recommended that the IC be operated at the stable region shown in Figure 94. It  
operates at the capacitance of more than 0.47μF. As capacitance is larger, stability becomes more stable and  
characteristic of output load fluctuation is also improved.

Notice  
Precaution on using ROHM Products  
(Note 1)  
1. If you intend to use our Products in devices requiring extremely high reliability (such as medical equipment  
,
aircraft/spacecraft, nuclear power controllers, 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  
ROHMs 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 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.
