Overview
The MC78M15ABDTRKG is a 500 mA positive voltage regulator from onsemi, part of the MC78M00/MC78M00A series. These regulators are designed for local, on-card voltage regulation and are similar to the MC7800 series but with half the output current. They are known for their ruggedness and reliability under various operating conditions, featuring internal current limiting, thermal shutdown circuitry, and safe-area compensation for the internal pass transistor.
