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.
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.
