● 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. T h e r e f o r e , i t i s i m p o r t a n t t o c o n s i d e r c i r c u i t p r o t e c t i o n m e a s u r e s , l i k e a d d i n g 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
For standby mode, set STBY voltage below 0.3V. For normal operation, set the pin voltage beyond 1.5V. It is not
recommended to set STBY voltage between 0.3V and 1.5V, as it may cause malfunctions.
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 the sudden accident. Please
avoid applications where the over current protection circuit operates continuously.
9) Thermal shutdown
This IC also features a thermal shutdown circuit that is designed to turn off the output when the junction temperature of
the IC exceeds about 170 ℃ . 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 applications. Therefore, it is not recommended
that you design application where TSD will work in normal condition.

10) Noise Pin
NOISE pin can drive small current, since it is directly connected to reference voltage circuit. The output voltage may
drop when the load of NOISE pin is more than 100nA. If the pin is connected to a capacitor, please use ceramic
capacitor for small leak current. Please take note that the output noise is smaller as NOISE pin capacitor is larger,
but startup time is longer.
11)Output capacitor
To prevent oscillation at output, it is recommended that the IC be operated at the stable region shown in Figure 12.
It operates at the capacitance value of more than 1.0 μ F. As capacitance is larger, stability becomes more stable and
characteristic of output load fluctuation is also improved.
