3 Description

The LMV431, LMV431A and LMV431B are precision

1.24 V shunt regulators capable of adjustment to 30

V. Negative feedback from the cathode to the adjust

pin controls the cathode voltage, much like a non-

inverting op amp configuration (Refer to Symbol and

Functional Diagrams). A two-resistor voltage divider

terminated at the adjust pin controls the gain of a

1.24 V band-gap reference. Shorting the cathode to the adjust pin (voltage follower) provides a cathode

voltage of a 1.24 V.

The LMV431, LMV431A and LMV431B have

respective initial tolerances of 1.5%, 1%, and 0.5%,

and functionally lend themselves to several

applications that require zener diode type

performance at low voltages. Applications include a 3 V to 2.7 V low drop-out regulator, an error amplifier in

a 3 V off-line switching regulator and even as a

voltage detector. These parts are typically stable with

capacitive loads greater than 10 nF and less than 50

pF.

The LMV431, LMV431A and LMV431B provide

performance at a competitive price.
