LM4431
Micropower Shunt Voltage Reference
General Description
Ideal for space critical applications, the LM4431 voltage ref-
erence 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 capaci-
tor 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 25C. Bandgap refer-
ence temperature drift curvature correction and low dynamic
impedance ensure stable reverse breakdown voltage accu-
racy over a wide range of operating temperatures and cur-
rents.
