APPLICATION
Oscillation Prevention on light loading conditions Recommended under circuit.
This IC requires 1MΩ resistance between INPUT and GND pin for clamp type input since the minute current
causes an unstable pin voltage.

This IC requires 1MΩ resistance between INPUT and GND pin for clamp type input since the minute current
causes an unstable pin voltage.
This IC requires 0.1μF capacitor between INPUT and GND, 1MΩ resistance between INPUT and GND for clamp
type input at mute mode.
