The role of a power management integrated circuit (PMIC), such as L4940D2T85-TR, is to convert one voltage form to another, usually a DC voltage form, while regulating the voltage levels. It is classified as a linear voltage regulator in the broad category of PMICs. Developed by STMicroelectronics, the L4940D2T85-TR has the capability to regulate current in the application field of automotive, industrial and general purpose. This device is capable of delivering up to 850mA current.

The principle of operation of voltage regulators is simple. When the input voltage does not match the output voltage, a voltage difference, also known as a voltage drop, is created that causes a current to flow from the input to the output. This is the regulation process. In the case of linear voltage regulators, the current is regulated using a voltage feedback loop that uses an operational amplifier and a control element. The operational amplifier computes the difference between the input voltage and the output voltage and adjusts the control element to regulate the voltage. This process is called linear regulation.

The L4940D2T85-TR is an adjustable linear voltage regulator featuring a wide input voltage range from 4.7V to 40V and an adjustable output voltage range from 1.21V to 36V.
