Input voltage pin - should be decoupled with 1µF or greater
capacitor.

Ground connection pin
Enable pin - this pin is internally pulled high. When pulled low
the PMOS pass transistor turns off and all internal circuitry
enters low-power mode, consuming less than 1µA.

OUT
Bypass capacitor connection - to improve AC ripple rejection,
connect a 10nF capacitor to GND. This will also provide a soft
start function.
2, 3, 4
Output pin - should be decoupled with 2.2µF capacitor.
