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.
