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 capacitor 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: 2.500V,
4.096V, 5.000V, 8.192V, and 10.000V. The minimum operating current increases from 60 A for the LM4040-
2.5 to 100 A for the LM4040-10.0. All versions have a maximum operating current of 15 mA.
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 breakdown voltage accuracy over a
wide range of operating temperatures and currents.
Also available is the LM4041 with two reverse breakdown voltage versions: adjustable and 1.2V. Please see
the LM4041 data sheet.
