MC79M12BTG Description

Short technical summary and product information.

The MC79M12BTG from ON Semiconductor is a 500mA negative voltage regulator designed as a complement to the MC78M00 series. It offers a fixed output voltage of -12V and is suitable for a wide range of applications requiring stable negative voltage regulation.

 

Key features include internal thermal overload protection and internal short-circuit current limiting, making the device remarkably rugged under most operating conditions. The output transistor also includes safe-area compensation. The regulator operates within a temperature range of -40°C to 125°C.

 

This device is available in a TO-220 package, designed for through-hole mounting. It requires no external components for basic operation, simplifying circuit design. The typical voltage dropout is 1.1V at 500mA, and it offers a PSRR of 60dB at 120Hz.
