Description
1
VOUT
Regulated Output Voltage. Bypass VOUT to GND with a 1 F or greater capacitor.
2
VOUT
Regulated Output Voltage. Bypass VOUT to GND with a 1 F 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
Ground.
5
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
No Connect. This pin is not connected internally.
7
VIN
Regulator Input Supply. Bypass VIN to GND with a 1 F or greater capacitor.
8
VIN
Regulator Input Supply. Bypass VIN to GND with a 1 F or greater capacitor.
EPAD
The exposed pad must be connected to ground.
