Function
Input pin. It is recommended to bypass this pin with a 1µF capacitor.
Ground connection pin.
Output pin. This pin should be decoupled with a 1µF or larger capacitor.
Not connected.
Enable input. Active high, logic level compatible.
Power-OK output pin. This pin is pulled to ground during a power failure; it
is normally high impedance and should have a 100kΩ pull-up resistor con-
nected to OUT.
