○ ORERATION NOTES

1.) Absolute Maximum Ratings

This product is produced with strict quality control, however, may be destroyed if it is operated beyond its absolute maximum ratings. If

the device is destroyed in exceeding the recommended maximum ratings, the failure mode will be difficult to determine (E.g. short mode,

open mode). Therefore, physical protection counter-measures (like fuse) should be implemented when operating conditions are

beyond the absolute maximum ratings specified.

2.) GND Potential

GND potential must be the lowest potential no matter what may happen. Actually, including transitional states, all pins except GND must

not be the voltage below GND.

3.) Setting of Heat

Consider Pd of actually using states, carry out the heat design that have adequate margin.

4.) Pin Short and Mistake Fitting

When mounting the IC on the PCB, pay attention to the orientation of the IC. If there is a placement mistake, the IC may be burned up.

5.) Actions in Strong Magnetic Field

Using the IC within a strong magnetic field may cause a 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.) Voltage of STBY Pin

For standby mode, set STBY voltage below 1.1V. For normal operation, set the pin voltage beyond 2.5V. It is not recommended to set

STBY voltage between 1.1V and 2.5V, and it may cause improper operation. And, please be sure to turn STBY Control Voltage ON from

OFF after applying Operating Voltage on VIN pin.

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 is effective in the destructive prevention by the sudden accident, please avoid use to which a 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 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 the

application as TSD working in normally condition.

10.) SS Pin

SS pin can drive quite small current, because the pin is directly connected to reference voltage circuit. It may be that output voltage is

dropping when the load of SS pin is more than 100nA. If the pin is connected to a capacitor, please use a ceramic capacitor for small

leak current. Please take care that output noise is smaller as SS pin capacitor is larger, but startup time is longer.

11.) Input / Output Capacitor

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 VIN. The higher

ESR (Ω)

CIN=4.7μF , COUT=4.7μF , Temp=25℃

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. Fig4 is the relation of IOUT and

ESR.. 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.
