MC79M12CDTRK Description

Short technical summary and product information.

The MC79M12CDTRK from On Semiconductor is a 500mA negative fixed voltage regulator, part of the MC79M00 series. This device provides a stable -12V output voltage and is suitable for applications requiring up to 500mA of current.

 

Key features include internal thermal overload protection and internal short-circuit current limiting, enhancing its ruggedness under various operating conditions. The regulator is designed for surface mount applications, utilizing the DPAK (TO-252-3) package.

 

With a nominal output voltage of -12V and an output current capability of 500mA, the MC79M12CDTRK is a complementary device to the MC78M00 series. It requires no external components for basic operation and offers a PSRR of 60dB at 120Hz. The operating temperature range is 0°C to 125°C.

 

This regulator is ideal for power supply applications where a fixed negative voltage is required. Its integrated protection features simplify circuit design and improve reliability. The surface mount DPAK package allows for efficient integration into compact electronic systems.
