Description
Regulator Input Supply. Bypass VIN to GND with a 1 µF or greater capacitor.
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. Not connected internally.
Regulated Output Voltage. Bypass VOUT to GND with a 1 µF or greater capacitor.
No Connect. Not connected internally.
Exposed Pad. The exposed pad must be connected to ground. The exposed pad enhances
the thermal performance of the package.
