LM4431
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 m A. 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. n Tolerates capacitive loads n Fixed reverse breakdown voltage of 2.50V Key Specifications n n n n n Output voltage tolerance 25˚C: ± 2.0% (max) Low output noise (10 Hz to 10 k Hz): 35 µVrms (typ) Wide operating current range: 100 µA to 15 m A mercial temperature...
