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.
Adjust. A resistor divider from VOUT to ADJ sets the output voltage.
Regulated Output Voltage. Bypass VOUT to GND with a 1 μF or greater capacitor.
