Pin Functions

PIN I/O DESCRIPTION
NAME NO.
EN 3 I Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown mode. See Enable Pin and Shutdown for more information. EN can be connected to IN if not used.
FB 4 I FB pin for 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.
GND 2 G Ground
IN 1 P Input supply
NR 4 I NR pin for fixed voltage versions only—connecting an external capacitor to this pin bypasses noise generated by the internal bandgap, reducing output noise to very low levels.
OUT 5 P Output of the regulator. There are no output capacitor requirements for stability.
