DESCRIPTION
NAME (DBV)
PIN NO.
IN 1 Unregulated input supply
GND 2 Ground
Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown
EN 3 mode. Refer to the Shutdown section under Application Information for more details. EN 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 4
internal bandgap, reducing output noise to very low levels.
Adjustable voltage version only — this is the input to the control loop error amplifier, and is used to set the
FB 4
output voltage of the device.
OUT 5 Output of the regulator. There are no output capacitor requirements for stability.
