Working Principle

The MC79M08BDTRK is an adjustable low dropout voltage regulator, which uses a voltage divider network to form a feedback loop that monitors the load voltage and keeps it at the desired level. The output of the feedback loop is compared to an internal reference voltage in a voltage comparator. The error signal is then amplified and used to drive the pass element, which consists of a low dropout PNP transistor. When the pass element is driven on, the output voltage is regulated at the desired set point.

The MC79M08BDTRK provides several features including thermal protection, current limiting, low dropout voltage and active high current limiting. It is designed to vastly reduce the number of components required for a given application and to improve efficiency.

The MC79M08BDTRK is a high-performance voltage regulator with precision, accuracy, and low power consumption, making it ideal for a multitude of applications. It is a reliable solution for providing highly accurate voltage sources for both digital and analog applications.
