LM4041  
Precision Micropower Shunt Voltage Reference  
General Description  
Key Specifications (LM4041-1.2)  
Ideal for space critical applications, the LM4041 precision  
voltage reference is available in the sub-miniature SC70 and  
SOT-23 surface-mount packages. The LM4041’s advanced  
design eliminates the need for an external stabilizing capaci-  
tor while ensuring stability with any capacitive load, thus  
making the LM4041 easy to use. Further reducing design  
effort is the availability of a fixed (1.225V) and adjustable  
reverse breakdown voltage. The minimum operating current  
is 60 µA for the LM4041-1.2 and the LM4041-ADJ. Both  
versions have a maximum operating current of 12 mA.
