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.
Output pin; should be decoupled with 2.2µF ceramic capacitor.
