LM4040  
Precision Micropower Shunt Voltage Reference  
n Fixed reverse breakdown voltages of 2.048V,  
2.500V,3.000V, 4.096V, 5.000V, 8.192V, and 10.000V  
General Description  
Ideal for space critical applications, the LM4040 precision  
voltage reference is available in the sub-miniature SC70 and  
SOT-23 surface-mount package. The LM4040’s advanced  
design eliminates the need for an external stabilizing capaci-  
tor while ensuring stability with any capacitive load, thus  
making the LM4040 easy to use. Further reducing design  
effort is the availability of several fixed reverse breakdown  
voltages: 2.048V, 2.500V, 3.000V, 4.096V, 5.000V, 8.192V,  
and 10.000V. The minimum operating current increases from  
60 µA for the LM4040-2.5 to 100 µA for the LM4040-10.0. All  
versions have a maximum operating current of 15 mA.

Extended temperature range  
Low temperature coefficient  
The LM4040 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

Also available is the LM4041 with two reverse breakdown  
voltage versions: adjustable and 1.2V. Please see the
