Overview
The MC78M05ACDTRKG is a positive linear voltage regulator from onsemi, part of the MC78M00 series. This regulator is designed for local, on-card voltage regulation and is similar to the popular MC7800 Series devices but with half the output current. It offers a maximum output current of 500 mA with adequate heatsinking and features internal current limiting, thermal shutdown circuitry, and safe-area compensation for the internal pass transistor, making it robust under most operating conditions.
