LM9140  
Precision Micropower Shunt Voltage Reference  
n Tolerates capacitive loads  
n Fixed reverse breakdown voltages of 2.500V, 4.096V,  
5.000V, and 10.000V  
General Description  
The LM9140’s reverse breakdown voltage temperature coef-  
±
ficients of 25 ppm/˚C are ideal for precision applications.  
The LM9140’s advanced design eliminates the need for an  
external stabilizing capacitor while ensuring stability with any  
capacitive load, thus making the LM9140 easy to use. Fur-  
ther reducing design effort is the availability of several fixed  
reverse breakdown voltages: 2.500V, 4.096V, 5.000V, and  
10.000V. The minimum operating current increases from  
60 µA for the LM9140-2.5 to 100 µA for the LM9140-10.0. All  
versions have a maximum operating current of 15 mA.

n Low output noise (10 Hz to 10 kHz): 35 µVrms (typ)  
n Wide operating current range: 60 µA to 15 mA  
n Industrial temperature range: −40˚C to +85˚C  
The LM9140 utilizes fuse and zener-zap reverse breakdown  
voltage trim during wafer sort to ensure that the prime parts
