LM4040

Precision Micropower Shunt Voltage Reference

n Fixed reverse breakdown voltages of 2.048V,

2.500V,3.000V, 4.096V, 5.000V, 8.192V, and 10.000V

General Description

Ideal for space critical applications, the LM4040 precision

voltage reference is available in the sub-miniature SC70 and

SOT-23 surface-mount package. The LM4040’s advanced

design eliminates the need for an external stabilizing capaci-

tor while ensuring stability with any capacitive load, thus

making the LM4040 easy to use. Further reducing design

effort is the availability of several fixed reverse breakdown

voltages: 2.048V, 2.500V, 3.000V, 4.096V, 5.000V, 8.192V,

and 10.000V. The minimum operating current increases from

60 µA for the LM4040-2.5 to 100 µA for the LM4040-10.0. All

versions have a maximum operating current of 15 mA.

Key Specifications (LM4040-2.5)

Output voltage tolerance

(A grade, 25˚C)

0.1% (max)

Low output noise

(10 Hz to 10 kHz)

35 µV_rms(typ)

60 µA to 15 mA

−40˚C to +85˚C

−40˚C to +125˚C

100 ppm/˚C (max)

Wide operating current range

Industrial temperature range

Extended temperature range

Low temperature coefficient

The LM4040 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.
