Precision Micropower Shunt Voltage Reference

Microchip Technology

Ideal for space critical applications, the LM4041 precision voltage reference is available in the subminiature (3mm x 1.3mm) SOT-23 surface mount package.

Product Description

The LM4041’s advanced design eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, making it easy to use.

The LM4041 utilize zener-zap reverse breakdown voltage trim during wafer sort. 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.
