Table 5. Pin Function Descriptions Mnemonic Pin No. ADP124 ADP125 Description
1 VOUT VOUT Regulated Output Voltage. Bypass VOUT to GND with a 1 μF or greater capacitor. 2 VOUT VOUT Regulated Output Voltage. Bypass VOUT to GND with a 1 μF or greater capacitor. 3 VOUT SENSE N/A Feedback Node for the Error Amplifier. Connect to VOUT. N/A ADJ Feedback Node for the Error Amplifier. Connect the midpoint of an external divider from VOUT to GND to this pin to set the output voltage. 4 GND GND Ground. 5 EN EN Enable Input. Drive EN high to turn on the regulator; drive EN low to turn off the regulator. For automatic startup, connect EN to VIN. 6 NC NC No Connect. This pin is not connected internally. 7 VIN VIN Regulator Input Supply. Bypass VIN to GND with a 1 μF or greater capacitor. 8 VIN VIN Regulator Input Supply. Bypass VIN to GND with a 1 μF or greater capacitor. EPAD EPAD The exposed pad must be connected to ground. Rev.
