Pinout and package

Pin	Name	Function	Source
1		OUT, Regulator output. A capacitor ≥ 2.2 μF must be tied from this pin to ground to ensure stability.
2		FB, Input to the error amplifier. FB is used to set the output voltage of the device.
3		NC, Not internally connected. This pin can either be left open or tied to GND.
4		GND, Ground
5		EN, This pin turns the regulator on or off. If VEN ≥ VEN(high), the regulator is enabled. If VEN ≤ VEN(low), the regulator is disabled.
6		NR/SS, Noise-reduction pin. Connecting an external capacitor to this pin bypasses noise generated by the internal band gap. This capacitor allows RMS noise to be reduced to very low levels and also controls the soft-start function.
7		DNC, Do not connect. Do not route this pin to any electrical net, not even GND or IN.
8		IN, Input supply
PowerPAD		PowerPAD, Must either be left open or tied to ground. Solder to the printed-circuit-board (PCB) plane to enhance thermal performance.
