PIN Type(1) DESCRIPTION
NAME SOT-223 VSON WSON
IN 1 8 6 I Unregulated input supply
GND 3, 6 4, Pad 3, Pad — Ground
EN 5 5 4 I Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown mode. See the Section 6.3.3 section for more details. EN must not be left floating and can be connected to IN if not used.
NR 4 3 2 — Fixed voltage versions only—connecting an external capacitor to this pin bypasses noise generated by the internal band gap, reducing output noise to very low levels.
FB 4 3 2 I Adjustable voltage version only—this is the input to the control loop error amplifier, and is used to set the output voltage of the device.
OUT 2 1 1 O Regulator output. A 1.0-μF or larger capacitor of any type is required for stability.
NC — 2, 6, 7 5 — Not connected
(1) I = Input; O = Output
