PIN TYPE DESCRIPTION
NAME SOT-23 WSON
EN 3 4 I Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown mode. EN can be connected to IN if not used.
FB — 2 I Adjustable version only; this pin is the input to the control loop error amplifier, and is used to set the output voltage of the device.
GND 2 3, Pad — Ground. The pad must be tied to GND.
IN 1 6 I Input supply.
N/C — 5 — Not internally connected. This pin must either be left open or tied to GND.
NR 4 2 — Fixed-voltage versions only; connecting an external capacitor to this pin bypasses noise generated by the internal band gap. This capacitor allows output noise to be reduced to very low levels.
OUT 5 1 O Output of the regulator. A small capacitor (total typical capacitance ≥ 2 μF ceramic) is needed from this pin to ground to ensure stability.
