LM4041 Precision Micropower Shunt Voltage Reference
January 2001
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鈥檚 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 碌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
卤
0.1%
(A grade) at 25藲C. 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.
