Pin Functions

PIN I/O DESCRIPTION
NAME NO.
SOT-23 DSBGA
EN 3 A3 I Enable pin. 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 N/A I Feedback pin. This terminal is the feedback input pin for the adjustable device. Fixed-voltage versions in the DBV package do not have this pin.
GND 2 A1 Regulator ground.
IN 1 C3 I Input to the device.
OUT 6 C1 O Output of the regulator.
NR 4 B2 Noise Reduction pin. Connecting an external capacitor to this pin filters noise generated by the internal bandgap. This configuration improves power-supply rejection and reduces output noise.
