Product Summary

The LM4040AEM3-5.0+T is a precision two-terminal shunt mode, bandgap voltage reference available in fixed reverse breakdown voltages of 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Ideal for space-critical applications, the LM4040AEM3-5.0+T is offered in the subminiature 3-pin SC70 surface-mount package (1.8mm×1.8mm), 50% smaller than comparable devices in SOT23 surfacemount packages (SOT23 versions are also available). The applications of the LM4040AEM3-5.0+T include Portable, Battery-Powered Equipment, Notebook Computers, Cell Phones, and Industrial Process Controls.
