Function
Power Switch input.
Ground.
Output voltage feedback input.
Shutdown control input, active low.
Analog and Power input.
SW(Pin 1):
Switch Pin. This is the drain of the internal
NMOS power switch. Minimize the metal trace area con-
nected to this pin to minimize EMI.
GND(Pin 2):
Ground Pin. Tie directly to ground plane.
FB(Pin 3):
Feedback Pin. Set the output voltage by selecting
values for R1 and R2 using:
Connect the ground of the feedback network to an AGND
plane which should be tied directly to the GND pin.
SHDN(Pin 4):
Shutdown Pin. The shutdown pin is an active
low control. Tie this pin above 1.1V to enable the device. Tie
this pin below 0.3V to turn off the device.
V
(Pin 5):
Input Supply Pin. Bypass this pin with a capacitor
as close to the device as possible.
