Description
This pin is internally connected to ground.
Adjust. A resistor divider from OUT to ADJ sets the output voltage.
Regulator Input Supply. Bypass IN to GND with a 1 µF or greater capacitor.
Regulated Output Voltage. Bypass OUT to GND with a 1 µF or greater capacitor.
Enable Input. Drive EN high to turn on the regulator; drive it low to turn off the regulator. For
automatic startup, connect EN to IN.
