Overview
The MC78M12BDTG is a part of the MC78M00/MC78M00A series of positive linear voltage regulators produced by onsemi. These regulators are similar to the 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 MC78M12BDTG specifically provides a fixed output voltage of 12 V and a maximum output current of 500 mA with adequate heatsinking.
