DIS 1 3
Discharge pin. If DIS pin is tied to OUT pin externally, the output voltage
will be discharged to ground when disabled.
GND 2 2 Ground.
OUT 3 1
Voltage output pin. This is the pin to the P-channel MOSFET drain.
Bypass to ground through a 0.1uF capacitor.
IN 4 5, 6
Voltage input pin. This is the pin to the P-channel MOSFET source.
Bypass to ground through a 1µF capacitor.
EN 5 4 Enable input, active high
