Pin Functions

PIN I/O DESCRIPTION
NAME SOT223
TO-263		 VSON
EN 1 8 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 5 5 I This terminal is the feedback input voltage for the adjustable device.
GND 3, Tab 6, PowerPAD — Regulator ground
IN 2 1, 2 I Unregulated input to the device.
N/C — 7 — Not internally connected. This pin must either be left open, or tied to GND.
NR 5 5 — Connecting an external capacitor to this pin bypasses noise generated by the internal bandgap. This improves power-supply rejection and reduces output noise.
OUT 4 3, 4 O Output of the regulator.
