Overview
The NCV78M05BDTRKG is a 5.0 V positive voltage regulator from onsemi, part of the MC78M00/MC78M00A and NCV78M00 series. This three-terminal regulator is designed for local, on-card voltage regulation and is specified for a maximum output current of 500 mA with adequate heatsinking. It is particularly robust due to its internal current limiting, thermal shutdown circuitry, and safe-area compensation for the internal pass transistor.
