1 A1 6 VIN Regulator Input Supply. Bypass VIN to GND with a 1 µF or greater capacitor. 2 B2 3 GND Ground. 3 B1 4 EN Enable Input. Drive EN high to turn on the regulator and drive EN low to turn off the regulator. For automatic startup, connect EN to VIN. 4 Not applicable 2 NC No Connect. Not connected internal y. 5 A2 1 VOUT Regulated Output Voltage. Bypass VOUT to GND with a 1 µF or greater capacitor. Not applicable Not applicable 5 NC No Connect. Not connected internal y. Not applicable Not applicable EPAD Exposed Pad. The exposed pad must be connected to ground. The exposed pad enhances the thermal performance of the package. Rev.
