Function
Input voltage pin – should be decoupled with 1µF or greater capacitor.
Ground connection pin
Enable pin – pin is internally pulled high. When pulled low the PMOS pass transistor
turns off and the device enters low-power mode, consuming less than 1µA.
Bypass capacitor connection -- to improve AC ripple rejection, connect a 1nF
capacitor to GND. This will also provide a soft start function.
Output pin – should be decoupled with 2.2µF or greater output capacitor. See
Detailed Description section for further information.
