General Description

Ideal for space critical applications, the LM4040 and LM4041

precision voltage references are available in the subminiature

(3mm × 1.3mm) SOT-23 surface-mount package.

The LM4040 is the available in ﬁxed reverse breakdown

voltages of 2.500V, 4.096V and 5.000V. The LM4041 is avail-

able with a ﬁxed 1.225V or an adjustable reverse breakdown

voltage.

The minimum operating current ranges from 60µA for the

LM4041-1.2 to 74µA for the LM4040-5.0. LM4040 versions

have a maximum operating current of 15mA. LM4041 ver-

sions have a maximum operating current of 12mA.

The LM4040 and LM4041 have bandgap reference tempera-

ture drift curvature correction and low dynamic impedance,

ensuring stable reverse breakdown voltage accuracy over a

wide range of operating temperatures and currents.
