Power Management Integrated Circuits - Voltage References

Power management integrated circuits (PMICs) are complex and high- performance semiconductor devices that enable efficient power management in a variety of applications.

Voltage references are specialized ICs that are used to accurately deliver a stable reference voltage in demanding applications. A voltage reference provides a stable output voltage over a wide range of input voltage and temperature variations. This allows it to serve as an accurate reference for other electronic circuits. Voltage references are also known as voltage reference circuits or precision voltage references. The LM4040DIM3-2.5/NOPB is an example of a voltage reference integrated circuit.
