DESCRIPTION
Ideal for space critical applications, the LM4040-N precision voltage reference is available in the subminiature SC70 and SOT-23 surface-mount package. The LM4040-N's advanced design eliminates the need for an external stabilizing capacitor whileensuring stability with any capacitive load, thusmaking the LM4040-N 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 uA for the 2.5-V LM4040-N to 100 uA for the 10.0-V LM4040-N. All versions have a maximum operating current of 15mA.
The LM4040-N 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℃. 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-N with two reversebreakdown voltage versions: adjustable and 1.2V. Please see the LM4041-N data sheet.
