ONSEMI MC78M12CDTG Voltage Regulator

The MC78M12CDTG is a positive linear voltage regulator similar to the MC7800 series but designed to provide half the typical output current. It features three-terminal regulation suitable for local, on-board applications. Built-in internal components include current limiting, thermal shutdown, and safe-area compensation for the pass transistor, ensuring robustness across operating conditions. It can deliver a maximum output current of up to 500mA with adequate heat sinking. The device requires no external components and offers internal thermal overload protection, short-circuit current limiting, and safe-area transistor compensation. Primarily used in power management applications.
