MC79M12CTG Description

Short technical summary and product information.

The MC79M12CTG from ON Semiconductor is a 500 mA negative voltage regulator. It is designed as a complement to the popular MC78M00 series. This device features internal thermal overload protection and internal short circuit current limiting, making it a robust choice for various power supply applications.

 

With a fixed output voltage of -12V, the MC79M12CTG is suitable for applications requiring a stable negative voltage rail. It operates within a temperature range of 0°C to 125°C and has an input voltage rating of up to -35V. The regulator is packaged in a TO-220-3 configuration, designed for through-hole mounting.

 

Key electrical characteristics include a typical PSRR of 60dB at 120Hz and a voltage dropout of 1.1V at 500mA. The device also incorporates output transistor safe-area compensation. Its fixed output type and negative polarity make it a straightforward component for power management circuits.
