LM4041
Precision Micropower Shunt Voltage Reference
General Description
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 A for the LM4041-1.2 and the LM4041-ADJ. Both
versions have a maximum operating current of 12 mA.
The LM4041 utilizes fuse and zener-zap reverse breakdown
or reference voltage trim during wafer sort to ensure that the
prime parts have an accuracy of better than ±0.1%
(A grade) at 25C. Bandgap reference temperature drift cur-
vature correction and low dynamic impedance ensure stable
reverse breakdown voltage accuracy over a wide range of
operating temperatures and currents.
