LM4050

Precision Micropower Shunt Voltage Reference

n Tolerates capacitive loads

n Fixed reverse breakdown voltages of 2.048V, 2.500V,

4.096V, 5.000V, 8.192V, and 10.000V

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.

Key Specifications (LM4050-2.5)

Output voltage tolerance

(A grade, 25˚C)

0.1% (max)

Low output noise

(10 Hz to 10 kHz)

41 µV_rms(typ)

60 µA to 15 mA

−40˚C to +85˚C

−40˚C to +125˚C

50 ppm/˚C (max)

Wide operating current range

Industrial temperature range

Extended temperature range

Low temperature coefficient

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 25˚C.

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.

Applications

n Portable, Battery-Powered Equipment

n Data Acquisition Systems

n Instrumentation

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).

n Process Control

n Energy Management

n Product Testing

n Automotive

Features
