Pin Functions

PIN I/O DESCRIPTION
NAME NO.
EN 5 I Driving this pin high turns on the regulator. Driving this pin low puts the regulator into shutdown mode. Refer to the Shutdown section for more details. EN must not be left floating and can be connected to IN if not used.
FB 3 I This pin is the input to the control-loop error amplifier and is used to set the output voltage of the device.
GND 4, pad — Ground
IN 7 I Unregulated input supply
8
NR 6 — Connect an external capacitor between this pin and ground to reduce output noise to very low levels. The capacitor also slows down the VOUT ramp (RC softstart).
OUT 1 O Regulator output. A 4.7-μF or larger capacitor of any type is required for stability.
