2 In use of ON/OFF CONTROL:
%Noise bypass Capacitance Cp
1 In the case where ON/OFF Control is not required:
Noise bypass capacitance Cp reduces noise generated by band-gap reference circuit.
Noise level and ripple rejection will be improved when larger Cp is used.
Use of smaller Cp value may cause oscillation.
Use the Cp value of 0.01 F greater to avoid the problem.
Connect control terminal to V
The quiescent current can be reduced by using a resistance “R”. Instead, it increases the minimum operating
voltage. For further information, please refer to Figure “Output Voltage vs. Control Voltage”.
