The NCV8502PDW50Gvoltage regulator is a dedicated linear regulator from On Semiconductor. It is an PMIC or Power Management Integrated Circuit, along with the majority of voltage regulators, falls into the category of linear regulators.

Linear regulators are some of the most widely used power supply circuits today and offer simple, straightforward implementation in a variety of applications. They take AC input voltage and reduce it to the desired DC output voltage, typically through a step-down voltage converter. This makes them useful for converting AC to DC power sources as well as providing a regulated output when the input voltage may change. In addition, they can be used to provide power to systems that require low ripple noise. Lastly, they are also very efficient when compared to switching regulators and offer better transient response times.

The NCV8502PDW50G is a simple, low power linear voltage regulator specifically designed for automotive applications. It is a fixed output voltage regulator designed for a regulated low-side output originating from a 12V or higher unregulated power supply. This integrates various functionalities such as over voltage protection (OVP), under voltage lockout (UVLO) and over temperature protection (OTP).

The working principle involves creating a voltage divider through two circuits: the series resistance and the output voltage. Together, they produce a stable, regulated output voltage by using the inherent characteristics of the two circuits. The part of the voltage divider created by the series programmable resistance will be the output voltage, while the part created by the output voltage will depend on the type of output voltage the circuit is required to provide. When the output voltage is constant, the output of the circuit is also stable.
