LM4050 Precision Micropower Shunt Voltage Reference
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 design 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: 2.500V, 4.096V, 5.000V, 8.192V, and 10.000V. The minimum operating current increases from 60 µA for the LM4050-2.5 to 100 µA for the LM4050-10.0. All versions have a maximum operating current of 15 mA. 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 breakdown voltage accuracy over a wide range of operating temperatures and currents. 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 Fixed reverse breakdown voltages of 2.500V, 4.096V, 5.000V, 8.192V, and 10.000V
