Table 1. PIN DESCRIPTIONS
NAME PIN NO. DESCRIPTION
IN 7, 8 Unregulated input supply.
GND 4, pad Ground.
Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown
EN 5 mode. Refer to Shutdown in the Application Information section for more details. EN must not be left floating
and can be connected to IN if not used.
Connect an external capacitor between this pin and ground to reduce output noise to very low levels. Also,
NR 6
the capacitor slows down the V
OUT
ramp (RC softstart).
Adjustable voltage version only. This pin is the input to the control loop error amplifier and is used to set
FB 3
the output voltage of the device.
Fixed voltage versions only. This pin is the input to the control loop error amplifier and is used to set the
SNS 3
output voltage of the device. This pin is to be shorted to OUT at load devices.
OUT 1, 2 Regulator output. A 4.7μF or larger capacitor of any type is required for stability.
