Overview
The MC78M05BDTRKG is a positive linear voltage regulator produced by onsemi. It is part of the MC78M00/MC78M00A series, which is similar to the popular MC7800 Series but specified for half the output current. These three-terminal regulators are designed for local, on-card voltage regulation and are known for their ruggedness under various operating conditions.
The MC78M05BDTRKG provides a fixed output voltage of 5V and can handle a maximum output current of 500 mA with adequate heatsinking. It features internal current limiting, thermal shutdown circuitry, and safe-area compensation for the internal pass transistor, making it highly reliable.
