Pin Functions

PIN TYPE DESCRIPTION
NO. NAME
1 SW Input 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.
2 GND — Ground - tie directly to ground plane.
3 FB Input Output voltage feedback input — set the output voltage by selecting values for R1 and R2 using: R1 = R2 × (VOUT / 1.237 V) –1
4 SHDN Input Active low shutdown - drive this pin to > 1.1 V to enable the device. Drive this pin to < 0.3 V to lace the device in a low-power shutdown.
5 VIN Input Analog and power input supply pin
