Pin Functions

PIN DESCRIPTION
NAME NO.
EN 5 Driving this pin high turns on the regulator. Driving this pin low puts the regulator into shutdown mode. See to the Shutdown section for more details. The EN pin must not be left floating and can be connected to the IN pin if not used.
FB/SNS 3 This pin is the input to the error amplifier and is used to set the output voltage of the device.
GND 4 Ground
IN 7 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 VO ramp (RC soft start).
OUT 1 Regulator output. A 4.7-μF or larger ceramic capacitor is required for stability.
2
Thermal Pad The Thermal Pad should be connected to GND.
