Product Introduction

Overview

The MC78M08CDTRK is a 500 mA positive voltage regulator from ON Semiconductor, part of the MC78M00/MC78M00A series. These regulators are designed for local, on-card voltage regulation and are similar to the popular MC7800 series but with half the output current. They are known for their robustness and reliability, featuring internal current limiting, thermal shutdown circuitry, and safe-area compensation for the internal pass transistor.
