Overview
The MC78M08CDTG is a Positive Voltage Regulator produced by ON Semiconductor. It is part of the MC78M00 series, which is identical to the popular MC7800 series but specified for only half the output current. This 3-terminal regulator is designed for local, on-card voltage regulation and features internal current limiting, thermal shutdown circuitry, and safe-area compensation for the internal pass transistor, making it remarkably rugged under most operating conditions. The device is suitable for applications requiring a fixed 8V output voltage and a maximum output current of 500 mA with adequate heat-sinking.
