DESCRIPTION
Input for voltage input. A 1µF or greater capacitor should be
placed in this pin.
Ground.
Enable pin. Pulling his pin low, can shut down the PMOS
pass transistor, and the current consuming can be set less
than 1µA.
Output voltage pin. The capacitor which connected between
this pin and GND should be decoupled with a 1µF or a
greater value low ESR ceramic capacitor.
Remote Sense.
Ground.
Bypass capacitor for noise reduction.
Enable Input.
Supply Input.
Output Voltage.
