LM4040/4041  
Precision Micropower Shunt Voltage Reference  
General Description  
Features  
Ideal for space critical applications, the LM4040 and LM4041  
precision voltage references are available in the subminia-  
ture (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  
available with a fixed 1.225V or an adjustable reverse break-  
down voltage.  
The LM4040 and LM4041’s advanced design eliminates the  
need for an external stabilizing capacitor while ensuring  
stability with any capacitive load, making them easy to use.  
Key Specifications  
• Output voltage tolerance (A grade, 25°C) .. ±0.1% (max)  
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  
versions have a maximum operating current of 12mA.  
• Low output noise (10Hz to 100Hz)  
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)  
The LM4040 and LM4041 utilizes zener-zap reverse break-  
down voltage trim during wafer sort to ensure that the prime  
parts have an accuracy of better than ±0.1% (A grade) at  
25°C. Bandgapreferencetemperaturedriftcurvaturecorrec-  
tion and low dynamic impedance ensure stable reverse  
breakdown voltage accuracy over a wide range of operating  
temperatures and currents.
