TYPICAL APPLICATION
Noise bypass Capacitance Cp
In the case of using a resistance "R" between V
Connect control terminal to V
State of control terminal:
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.
