General 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 A to 15 mA.
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.
