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.
