ADP222/ADP224 ADP223/ADP225 Mnemonic Description
1 1 EN1 Enable Input for the First
Regulator. Drive EN1 high to turn on Regulator 1 and drive
EN1 low to turn off Regulator 1. For automatic startup, connect EN1 to VIN.
2 2 EN2 Enable Input for the Second Regulator. Drive EN2 high to turn on Regulator 2 and
drive EN2 low to turn off Regulator 2. For automatic startup, connect EN2 to VIN.
3 3 GND Ground Pin.

1
SENSE2 Sense Pin for VOUT2.
5 5 VOUT2 Regulated Output Voltage. Connect an 1 µF or greater output capacitor between
VOUT2 and GND.
6 6 VIN Regulator Input Supply. Bypass VIN to GND with a 1 µF or greater capacitor.
7 7 VOUT1 Regulated Output Voltage. Connect 1 µF or greater output capacitor between
VOUT1 and GND.
