*Input Capacitance CIN
Input Capacitance (CIN)) is required to prevent oscillation and reduce power supply ripple for applications with high
power supply impedance or a long power supply line.
Use the CIN value of 0.1µF greater to avoid the problem.
CIN should connect between GND and VIN as short as possible.
*Output Capacitance CO
Output capacitor (CO) is required for a phase compensation of the internal error amplifier. The capacitance and the
equivalent series resistance (ESR) influences stability of the regulator.
This product is designed to work with a low ESR capacitor for the CO; however, use of recommended capacitance or
greater value is essential for stable operation.
Use of a smaller CO may cause excess output noise or oscillation of the regulator due to lack of the phase
compensation.
Therefore, use CO with the recommended capacitance or greater value and connect between VO terminal and
GND terminal with minimal wiring. The recommended capacitance depends on the output voltage. Low voltage
regulator requires greater value of the CO. Thus, check the recommended capacitance for each output voltage.
Use of a greater CO reduces output noise and ripple output, and also improves transient response of the output
voltage against rapid load change.
