MC79M12BDTRKG Description

Short technical summary and product information.

The ON Semiconductor MC79M12BDTRKG is a 500 mA negative voltage regulator from the MC79M00 series. It provides a fixed -12V output and is designed as a complement to the MC78M00 series.

 

This regulator features internal thermal overload protection and internal short-circuit current limiting, making it robust for various operating conditions. It also includes output transistor safe-area compensation. The device operates within a temperature range of -40°C to 125°C and has a maximum input voltage of -35 Vdc.

 

The MC79M12BDTRKG is available in a surface-mount DPAK package (TO-252-3, DPak). 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.

 

This component is suitable for applications requiring a stable negative voltage supply. Its integrated protection features contribute to system reliability.
