Pin Function

Enable input. Driving this pin high turns on the regulator. Driving this pin low shuts off the regula-

tor. If not driven from a control circuit, tie this pin to the VIN pin.

Input supply pin. A large bulk capacitance should be placed close to this pin to ensure that the

input supply does not sag below the minimum VIN. Also a minimum of 4.7uF ceramic capacitor

should be placed directly at this pin.

Regulator output pin. Refer to the Applications Information section for output capacitor selection.

Inverting input of the error amplifier. This pin is used to set the output voltage (See typical Applica-

tion Circuits on page 1).

Ground pin.

No connection.

The exposed pad enhances thermal performance and is not electrically connected to GND inside

the package. It is recommended to connect the exposed pad to the ground plane.
