DESCRIPTION

NAME

(DBV)

PIN NO.

IN

1

Input supply

GND

2

Ground

EN

3

Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the regulator into shutdown

mode. Refer to the Shutdown section under Applications Information for more details. EN can be connected to

IN if not used.

NR

4

Fixed voltage versions only—connecting an external capacitor to this pin bypasses noise generated by the

internal bandgap, reducing output noise to very low levels.

FB

4

Adjustable voltage version only—this is the input to the control loop error amplifier, and is used to set the

output voltage of the device.

OUT

5

Output of the regulator. There are no output capacitor requirements for stability.
