Overview
The MC78M15CDTRK 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 specified for half the output current. The MC78M15CDTRK is particularly suited for applications requiring a stable 15V output voltage.
