The MC78M05CDTRKG is a 500 mA positive voltage regulator designed to provide a fixed 5.0V output. This three-terminal regulator maintains an output voltage between 4.8V and 5.2V at 25°C and can deliver a peak output current of 700 mA. Key features include a typical dropout voltage of 2.0V, a minimum ripple rejection of 62 dB, and a maximum load regulation of 100 mV. The device incorporates internal thermal overload protection, short-circuit current limiting, and safe-area compensation. These integrated protections make it a rugged and reliable choice for local, on-card voltage regulation without the need for external components.
