Fonctionnalités et applications
The LM4041 is available with a fixed 1.225 V or an adjustable reverse breakdown voltage. The LM4040 and LM4041’s advanced design eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, making them easy to use.

The minimum operating current ranges from 60 µA for the LM4041-1.2 to 74 µA for the LM4040-5.0. LM4040 versions have a maximum operating current of 15 mA. LM4041 versions have a maximum operating current of 12 mA.

The LM4040 and LM4041 utilizes 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. The LM4040 and LM4041 precision voltage references are available in the subminiature (3 mm x 1.3 mm) SOT-23 surface-mount package.
