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

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 −40˚C and +85˚C. Selected parts can operate in the

extended temperature range, from −40˚C and +125˚C.
