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.
Power-OK Output. This open-drain output is low when OUT is out
of regulation. Connect a pull up resistor from POK to OUT or IN.
Output pin - should be decoupled with 2.2µF ceramic capacitor.
