Pin Function
Supply Input.
Ground.
Enable/Shutdown (Input): CMOS compatible input. Logic high = enable;
logic low = shutdown. Do not leave open.
Reference Bypass: Connect external 0.01µF ≤ C_BYP ≤ 1.0µF capacitor to
GND to reduce output noise. May be left open.
Regulator Output
No internal connection.
Ground: Internally connected to the exposed pad. Connect externally to
GND pin.
