Function
Input voltage pin; should be decoupled with 1µF or greater
capacitor.
Ground connection pin.
Enable pin. When pulled low, the PMOS pass transistor turns
off and all internal circuitry enters low-power mode, consuming
less than 1µA. This pin should not be left floating.
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 capacitor.
