LM4431  
Micropower Shunt Voltage Reference  
n Tolerates capacitive loads  
n Fixed reverse breakdown voltage of 2.50V  
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 µA to 15 mA.  
Key Specifications  
±
n Output voltage tolerance 25˚C: 2.0% (max)  
n Low output noise (10 Hz to 10 kHz): 35 µVrms (typ)  
n Wide operating current range: 100 µA to 15 mA  
n Commercial temperature range: 0˚C to +70˚C  
n Low temperature coefficient: 30 ppm/˚C (typ)  
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 refer-  
Applications  
n Portable, Battery-Powered Equipment  
n Data Acquisition Systems  
n Instrumentation  
ence temperature drift curvature correction and low dynamic  
impedance ensure stable reverse breakdown voltage accu-
