Pin Functions

PIN I/O DESCRIPTION
NAME NO.
IN 6 I Input supply.
GND 3, Pad — Ground. The pad must be tied to GND.
EN 4 I Driving this pin 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 2 I Adjustable voltage version only. Feedback; this pin is the input to the control loop error amplifier and sets the output voltage of the device.
OUT 1 O Output of the regulator. To assure stability, a small ceramic capacitor (total typical capacitance ≥ 2 μF) is required from this pin to ground.
N/C 5 — Not internally connected. This pin must either be left open or tied to GND.
