■ TYPICAL APPLICATION
1
○In the case where ON / OFF Control is not required :
Connect control terminal to VIN terminal
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”.
2
○In use of ON / OFF CONTROL :
State of control terminal :
●“H” → output is enabled.
●“L” or “open” → output is disabled.
*Noise bypass Capacitance Cp
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 0.01uF greater to avoid the problem.
