Description

1

VIN

Regulator Input Supply. Bypass VIN to GND with a 1 μF or greater capacitor.

2

GND

Ground.

3

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.

4

NC

No Connect. This pin is not connected internally.

5
