Note:
1. Output filtering capacitor C1 is a ceramic capacitor that is used to filter high frequency noise. C2 is an electrolytic capacitor. It is recommended to use high frequency and
low impedance electrolytic capacitors. For capacitance and current of capacitor please refer to the manufacturer’s datasheet. Voltage derating of capacitor should be 80%
or above.
