Regulator enable pin. Drive EN high to turn on the regulator; drive EN low to turn EN 3 3 B1 I off the regulator. For automatic startup, connect EN to IN directly. GND 2 2 B2 – Ground reference pin. Connect GND pin to PCB ground plane directly. IN 1 4 A1 I Input voltage pin. Bypass IN to GND with a 1 μF or greater capacitor. NC 4 – – – No connection. OUT 5 1 A2 O Regulated output voltage pin. Bypass OUT to GND with a 1 μF or greater capacitor. (1) Thermal Pad
MUST
be connected to PCB ground plane directly.
