5 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. OUT 7 r C r ~ =~= 100Ω C 20pF LPF 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. UNISONIC TECHNOLOGIES CO., LTD of 6
