LM4040/4041  
Precision Micropower Shunt Voltage Reference  
General Description  
Features  
Ideal for space critical applications, the LM4040 and LM4041  
precisionvoltagereferencesareavailableinthesubminiature  
(3mm × 1.3mm) SOT-23 surface-mount package.  
• Small SOT-23 package  
• No output capacitor required  
Tolerates capacitive loads  
• Fixed reverse breakdown voltages of 1.225, 2.500V,  
4.096V and 5.000V  
• Adjustable reverse breakdown version  
• Contact Micrel for parts with extended temperature  
range.  
The LM4040 is the available in fixed reverse breakdown  
voltages of 2.500V, 4.096V and 5.000V. The LM4041 is avail-  
able with a fixed 1.225V or an adjustable reverse breakdown  
voltage.  
The minimum operating current ranges from 60µA for the  
LM4041-1.2 to 74µA for the LM4040-5.0. LM4040 versions  
have a maximum operating current of 15mA. LM4041 ver-  
sions have a maximum operating current of 12mA.  
Key Specifications  
• Output voltage tolerance .............................±0.1% (max)  
• Low output noise (10Hz to 100Hz)  
The LM4040 and LM4041 have bandgap reference tempera-  
ture drift curvature correction and low dynamic impedance,  
ensuring stable reverse breakdown voltage accuracy over a  
wide range of operating temperatures and currents.  
LM4040................................................. 35µV  
LM4041................................................. 20µV  
• Wide operating current range  
LM4040..................................................60µA to 15mA  
LM4041..................................................60µA to 12mA  
• Industrial temperature range .................. –40°C to +85°C  
• Low temperature coefficient ................ 100ppm/°C (max)
