SNVS103C –JUNE 2000–REVISED APRIL 2013

LM4431 Micropower Shunt Voltage Reference

Check for Samples: LM4431

FEATURES

DESCRIPTION

Ideal for space critical applications, the LM4431

voltage reference is available in the sub-miniature

(3 mm x 1.3 mm) SOT-23 surface-mount package.

The LM4431's advanced design eliminates the need

for an external stabilizing capacitor while ensuring

stability with any capacitive load, thus making the

LM4431 easy to use. The operating current range is

100 μA to 15 mA.

•

Small Package: SOT-23

No Output Capacitor Required

Tolerates Capacitive Loads

Fixed Reverse Breakdown Voltage of 2.50V

APPLICATIONS

•

Portable, Battery-Powered Equipment

Data Acquisition Systems

Instrumentation

The LM4431 utilizes fuse and zener-zap reverse

breakdown voltage trim during wafer sort to ensure

that the parts have an accuracy of better than ±2.0%

at 25°C. Bandgap reference temperature drift

curvature correction and low dynamic impedance

ensure stable reverse breakdown voltage accuracy

over a wide range of operating temperatures and

currents.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
