Overview
The MC78M05ACDTRK is a 500 mA positive voltage regulator from onsemi, part of the MC78M00/MC78M00A Series. These regulators are similar to the popular MC7800 Series but are specified for half the output current. They are designed for local, on-card voltage regulation and are known for their ruggedness under various operating conditions. The MC78M05ACDTRK specifically provides a regulated output voltage of 5.0 V.
