LM4050  
Precision Micropower Shunt Voltage Reference  
n Tolerates capacitive loads  
n Fixed reverse breakdown voltages of 2.048V, 2.500V,  
4.096V, 5.000V, 8.192V, and 10.000V  
General Description  
Ideal for space critical applications, the LM4050 precision  
voltage reference is available in the sub-miniature (3 mm x  
1.3 mm) SOT-23 surface-mount package. The LM4050’s de-  
sign eliminates the need for an external stabilizing capacitor  
while ensuring stability with any capacitive load, thus making  
the LM4050 easy to use. Further reducing design effort is the  
availability of several fixed reverse breakdown voltages:  
2.048V, 2.500V, 4.096V, 5.000V, 8.192V, and 10.000V. The  
minimum operating current increases from 60 µA for the  
LM4050-2.0 to 100 µA for the LM4050-10.0. All versions  
have a maximum operating current of 15 mA.

Wide operating current range  
Industrial temperature range  
Extended temperature range  
Low temperature coefficient  
The LM4050 utilizes fuse and zener-zap reverse breakdown  
voltage trim during wafer sort to ensure that the prime parts  
have an accuracy of better than 0.1% (A grade) at 25˚C.  
Bandgap reference temperature drift curvature correction  
and low dynamic impedance ensure stable reverse break-  
down voltage accuracy over a wide range of operating tem-  
peratures and currents.  
Applications  
n Portable, Battery-Powered Equipment  
n Data Acquisition Systems  
n Instrumentation  
All grades and voltage options of the LM4050 are available  
in both an industrial temperature range (−40˚C and +85˚C)  
and an extended temperature range (−40˚C and +125˚C).
