Texas Instruments Voltage Reference, Precision Micropower, Shunt Fixed, SOT-23- - 1.225V

The Texas Instruments LM4040 Series Precision Micropower Shunt Voltage Reference is an advanced electronic component designed for reliable energy management and power regulation. Qualified to AEC-Q100 standards for automotive applications, this shunt-fixed voltage reference provides stable and accurate performance across a wide range of operating conditions. Its innovative design eliminates the need for an external stabilising capacitor while maintaining exceptional stability with any capacitive load, simplifying circuit design and reducing board space.

Engineered for precision, the LM4040 utilises fuse and zener-zap reverse breakdown voltage trim during wafer sort to achieve outstanding accuracy. Band-gap reference temperature drift curvature correction and low dynamic impedance work together to ensure stable reverse breakdown voltage accuracy over a broad spectrum of operating temperatures and currents. This device features a maximum operating current of 15 mA and does not require an output capacitor, making it incredibly easy to implement into existing systems.

Manufactured as an environmentally conscious green product, it contains no antimony (Sb) or bromine (Br). The surface-mount SOT-23-3 package ensures compatibility with modern automated assembly processes. This versatile voltage reference is ideally suited for a multitude of demanding applications, including portable devices, test and measurement equipment, sensing instrumentation, automation process control, power management systems, automotive electronics, and audio equipment.
