1 1 VIN Regulator Input Supply. Bypass VIN to GND with a 1 μF or greater capacitor. 2 2 GND Ground. 3 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. Not connected internally. 4 ADJ Adjust. A resistor divider from VOUT to ADJ sets the output voltage. 5 5 VOUT Regulated Output Voltage. Bypass VOUT to GND with a 1 μF or greater capacitor. Rev.
