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) SSOT-23 surface-mount package. The LM4050’s
design eliminates the need for an external stabilizing capaci-
tor while ensuring stability with any capacitive load, thus
making the LM4050 easy to use. Further reducing design ef-
fort is the availability of several fixed reverse breakdown volt-
ages: 2.500V, 4.096V, 5.000V, 8.192V, and 10.000V. The
minimum operating current increases from 60 μA for the
LM4050-2.5 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
±
0.1% (A grade) at 25C.
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 operate be-
tween 40C and +85C. Selected parts can operate in the
extended temperature range, from 40C and +125C.
