PIN TYPE DESCRIPTION
NAME NO.
SOT-23 SOT-223 VSON
IN 1 1 8 I Input supply.
GND 2 3, 6 4, Pad — Ground.
EN 3 5 5 I Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown mode. See the Enable Pin and Shutdown section under Feature Description for more details. Connect EN to IN if not used.
NR 4 4 3 — 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 4 3 I Adjustable voltage version only—this pin is the input to the control loop error amplifier, and is used to set the output voltage of the device.
OUT 5 2 1 O Output of the regulator. There are no output capacitor requirements for stability.
