TYPICAL APPLICATION
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.
Noise bypass Capacitance Cp
Connect control terminal to V
State of control 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”.
In use of ON/OFF CONTROL:
In case that ON/OFF Control is not required:
“H”
“L” or “open”
output is enabled.
