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: VIN VIN VOUT ＮＪＭ2863/64 0.1µF VOUT 1.0µF (ceramic) OR 2.2µF: Vo≤2.6V R NOISE CONTROL BYPASS GND Cp=0.01µF 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 0.01µF greater to avoid the problem.
