Description
Regulated Output Voltage. Bypass VOUT to GND with a 1 µF or greater capacitor.
Regulated Output Voltage. Bypass VOUT to GND with a 1 µF or greater capacitor.
Feedback Node for the Error Amplifier. Connect to VOUT.
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.
Ground.
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.
No Connect. This pin is not connected internally.
Regulator Input Supply. Bypass VIN to GND with a 1 µF or greater capacitor.
