Power Switch input.
This is the drain of the internal NMOS power switch.
Minimize the metal trace area connected to this pin to minimize EMI.
Ground. Tie directly to ground plane.
Output voltage feedback input.
Set the output voltage by selecting values for R1 and R2 using:
Connect the ground of the feedback network to a GND plane.
Enable, active high.
The enable pin is an active high control. Tie this pin above 2V to enable the
device. Tie this pin below 0.4V to turn off the device.
Analog and Power input. Input Supply Pin.
Place bypass capacitor as close to V
