LM4040AEM3-5.0/V+T

5.0 V High-Accuracy, Low-Drift Shunt Reference in SOT-23 Package

Product Description

Product Overview

The LM4040AEM3-5.0/V+T is a precision shunt voltage reference that provides a stable 5.000 V output with excellent initial accuracy and low temperature drift. Designed for precision analog and data-conversion systems, it operates over a wide range of shunt currents and maintains stability without requiring an external output capacitor. The compact SOT-23-3 package and low noise characteristics make it an ideal choice for ADC/DAC references, power-supply monitoring, and precision signal-conditioning applications.
