Pin Description
Input voltage pin.
It should be decoupled with 1µF or greater capacitor.
Ground connection pin.
Enable pin.
When pulled low, the PMOS pass transistor turns off, current
consuming less than 1µA.
Enable bar pin.
When pulled high, the PMOS pass transistor turns off, current
consuming less than 1µA.
The SR(Slew Rate) terminal is used to control the V_OUT in-rush
current.
LDO voltage regulator output pin.
It should be decoupled with a 4.7µF or greater value low ESR
ceramic capacitor.
