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”.

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.
