LM4041 Precision Micropower Shunt Voltage Reference
General Description
Ideal for space critical applications, the LM4041 precision voltage reference is available in the sub-miniature SC70 and SOT-23 surface-mount packages. The LM4041’s advanced design eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM4041 easy to use. Further reducing design effort is the availability of a fixed (1.225V) and adjustable reverse breakdown voltage. The minimum operating current is 60 A for the LM4041-1.2 and the LM4041-ADJ. Both versions have a maximum operating current of 12 mA. The LM4041 utilizes fuse and zener-zap reverse breakdown or reference voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than ± 0.1% (A grade) at 25C. 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.
