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
