Function
Input voltage pin; should be decoupled with 1µF or greater
capacitor.
Ground connection pin.
Enable pin; this pin should not be left floating. When pulled low,
the PMOS pass transistor turns off and all internal circuitry
enters low-power mode, consuming less than 1µA.
Bypass capacitor connection; to improve AC ripple rejection,
connect a 10nF capacitor to GND. This will also provide a soft-
start function.
Output pin; should be decoupled with 2.2µF ceramic capacitor.
