ENABLE: CMOS compatible control input.
Logic high = enable, logic low = shutdown.
INPUT: Supplies the current to the output power device
GND: TAB is also connected internally to the IC’s ground on D-PAK.
OUTPUT: The regulator output voltage
ADJUST: Adjustable regulator feedback input that connects to the resistor
voltage divider that is placed from OUTPUT to GND in order to set the
output voltage.
FLAG: Active low error flag output signal that indicates an output fault
