DESCRIPTION
NAME NO.
IN 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 the Shutdown section under Applications Information for more details. EN must not be left
floating and can be connected to IN if not used.
Fixed voltage versions only. Connecting an external capacitor to this pin bypasses noise generated by the
NR 3
internal bandgap, reducing output noise to very low levels.
Adjustable voltage version only. This is the input to the control loop error amplifier, and it is used to set the
FB 3
output voltage of the device.
OUT 1 Regulator output. A 1.0- µ F or larger capacitor of any type is required for stability.
NC 2, 6, 7 No internal connection
