LM4050
Precision Micropower Shunt Voltage Reference
General Description
Ideal for space critical applications, the LM4050 precision
voltage reference is available in the sub-miniature (3 mm x
1.3 mm) SOT-23 surface-mount package. The LM4050’s de-
sign eliminates the need for an external stabilizing capacitor
while ensuring stability with any capacitive load, thus making
the LM4050 easy to use. Further reducing design effort is the
availability of several fixed reverse breakdown voltages:
2.048V, 2.500V, 4.096V, 5.000V, 8.192V, and 10.000V. The
minimum operating current increases from 60 µA for the
LM4050-2.0 to 100 µA for the LM4050-10.0. All versions
have a maximum operating current of 15 mA.
The LM4050 utilizes fuse and zener-zap reverse breakdown
voltage trim during wafer sort to ensure that the prime parts
have an accuracy of better than
Bandgap reference temperature drift curvature correction
and low dynamic impedance ensure stable reverse break-
down voltage accuracy over a wide range of operating tem-
peratures and currents.
All grades and voltage options of the LM4050 are available
in both an industrial temperature range (−40˚C and +85˚C)
and an extended temperature range (−40˚C and +125˚C).
