Overview
The MC78M05ABDTRKG is a 500 mA 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.
