Pin Description
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:
R1 =
R

V _out
1.23V
− 1_{}
Connect the ground of the feedback network to an AGND(Analog Ground)
plane which should be tied directly to the GND pin.
Shutdown control input, active low.
The shutdown pin is an active low control. Tie this pin above 1V to enable
the device. Tie this pin below 0.4V to turn off the device.
Analog and Power input.
Input Supply Pin. Bypass this pin with a capacitor as close to the device
as possible.
