Pin Functions

PIN I/O DESCRIPTION
NAME VSON SOT-223
IN 1, 2 2 I Unregulated input to the device
GND 6 3, 6 — Regulator ground
EN 8 1 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.
NR 5 5 — Noise-reduction pin for fixed versions only. Connecting an external capacitor to this pin bypasses noise generated by the internal bandgap, which improves power-supply rejection and reduces output noise. (Not available on adjustable versions.)
FB 5 5 I Feedback input voltage for the adjustable device.
(Not available on fixed voltage versions.)
OUT 3, 4 4 O Regulator output
N/C 7 – — No internal connection
