3. Behavior When Power Is Turned ON/OFF
This IC performs a soft-start operation on power application. This is to prevent an overcurrent from flowing
through the IC on power application while the high-capacity capacitor connected to the output pin is charged.
Power ON: Soft start (2.5 to 8 ms)
Power OFF: No control (10 µs MAX.)
