PIN FUNCTIONS (DFN/TSOT)
FB (Pin 1/Pin 3): Feedback Pin. Reference voltage is 1.255V.
Connect resistive divider tap here. Minimize trace area at
FB. Set VOUT = 1.255V(1 + R1/R2).
GND (Pins 2, 5, 9/Pin 2): Ground. Tie directly to local
ground plane.
SW (Pins 3, 4/Pin 1): Switch Pin. (Collector of internal
NPN power switch) Connect inductor/diode here and
minimize the metal trace area connected to this pin to
minimize EMI.
VIN (Pin 6/Pin 6): Input Supply Pin. Must be locally
bypassed.
SS (Pin 7/Pin 5): Soft-Start Pin. Place a soft-start capacitor
here. Upon start-up, 4μA of current charges the capacitor
to 1.255V. Use a larger capacitor for slower start-up. Leave
oating if not in use.
SHDN (Pin 8/Pin 4): Shutdown Pin. Tie to 2.4V or more
to enable device. Ground to shut down.
