A1 VIN Regulator Input Supply. Bypass VIN to GND with a 1 µF or greater capacitor. A2 VOUT Output Voltage Adjust Input. Connect the midpoint of an external divider from VOUT to GND to this pin to set the output voltage B1 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. B2 GND Ground. Rev.
