MC79M05CT Description

Short technical summary and product information.

The ON Semiconductor MC79M05CT is a 500mA negative voltage regulator from the MC79M00 series. It provides a fixed -5V output and is designed for applications requiring a stable negative voltage rail. This device features internal thermal overload protection and internal short circuit current limiting, making it robust under various operating conditions.

 

The regulator has a typical voltage dropout of 1.1V at 500mA and offers a PSRR of 66dB at 120Hz. It operates within a temperature range of 0°C to 125°C. The MC79M05CT is supplied in a TO-220-3 package suitable for through-hole mounting.

 

This device is intended as a complement to the popular MC78M00 series of positive voltage regulators. Its fixed output voltage and integrated protection features simplify power supply designs.
