*Suggestion: Use tantalum type capacitor to reduce the ripple of the output voltage. Use 1nF filter ceramic type

capacitor to connect Vout pin and GND pin. The filter capacitor is recommended as close as possible to Vout pin

and GND pin.

Electrical Characteristics

Default condition (unless otherwise provided): Vin=0.6xVout, Iout=10mA.Temperature=25℃. Use external

circuit in test circuit list.
