Overview
The MC78M05ACDTG is a 500 mA positive linear voltage regulator from onsemi, part of the MC78M00/MC78M00A series. This regulator is identical to the popular MC7800 Series devices but is specified for only half the output current. It is designed for local, on-card voltage regulation and features internal current limiting, thermal shutdown circuitry, and safe-area compensation for the internal pass transistor, making it remarkably rugged under most operating conditions.
The MC78M05ACDTG is available in various packages, including DPAK-3 and TO-220, and offers high accuracy with a tolerance of ±2%. It operates within a temperature range of 0°C to +125°C and does not require any external components for operation.
