Overview
The MC78M05CDTT5G is a 500 mA positive voltage regulator from onsemi, part of the MC78M00/MC78M00A Series. These regulators are designed for local, on-card voltage regulation and are known for their robustness and reliability. They are similar to the MC7800 Series but with half the output current. The MC78M05CDTT5G specifically provides a regulated 5V output voltage.
