ONSEMI MC78M05CDTG 5 Volt Voltage Regulator

The MC78M05CDTG is a 5.0V positive voltage regulator designed for local, on-card regulation with no external components required. It features internal thermal overload protection, short circuit current limiting, and safe-area compensation for the internal pass transistor, ensuring rugged operation up to 125°C junction temperature. Suitable for automotive and industrial applications, the device offers maximum output current of 500 mA with proper heatsinking. Its low noise of 40 uV and excellent ripple rejection make it ideal for sensitive electronic circuits requiring stable voltage regulation in compact packages like DPAK and TO-220.
