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. *In the case of using a resistance "R" between VIN and control. If this resistor is inserted, the control current could be reduced when the control voltage is high. The applied voltage to control pin should set to consider voltage drop through the resistor “R” and the minimum control voltage for ON-state. The VCONT (ON) and ICONT have temperature dependence as shown in the "Control Current vs. Temperature" and " Control Voltage vs. Temperature" characteristics. Therefore, the resistor "R" should be selected to consider the temperature characteristics. -4- Ver.2017-06-29 NJM2881/82 *Input Capacitor CIN The input capacitor CIN is required in order to prevent oscillation and reduce power supply ripple of applications when high power supply impedance or a long power supply line. Therefore, the recommended capacitance (refer to conditions of ELECTRIC CHARACTERISTIC) or larger input capacitor, connected between VIN and GND as short path as possible, is recommended in order to avoid the problem. *Output Capacitor CO The output capacitor CO is required for a phase compensation of the internal error amplifier, and the capacitance and the equivalent series resistance (ESR) influence stable operation of the regulator. If use a smaller output capacitor than the recommended capacitance (refer to conditions of ELECTRIC CHARACTERISTIC), it may cause excess output noise or oscillation of the regulator due to lack of the phase compensation. Therefore, the recommended capacitance or larger output capacitor, connected between VOUT and GND as short path as possible, is recommended for stable operation. The recommended capacitance may be different by output voltage, therefore confirm the recommended capacitance of the required output voltage. Furthermore, a larger output capacitor reduces output noise and ripple output, and also improves Output Transient Response when a load changes rapidly. Selecting the output capacitor, should consider varied characteristics of a capacitor: frequency characteristics, temperature characteristics, DC bias characteristics and so on. Therefore, the capacitor that has a sufficient margin of the rated voltage against the output voltage and superior temperature characteristics, is recommended for CO.
