NOTES ON USE
1. Please use the IC & external components: within the specified electrical characteristics range and ensure that
absolute maximum ratings are not exceeded.
2. For C1 & C2, please use a capacitor with as small an ESR value as possible.
3. In order to reduce impedance between the IC's input pin and the power supply, we recommend that a capacitor (C
IN
)
be connected to the input side.
4. If an external power supply is applied to the output pin in order to have V
OUT
connected to GND during standby,
large current flows through the IC are a possibility.

Further, do not use a capacitor at C2 that has a large
