MC78M12CT Description

Short technical summary and product information.

The MC78M12CT from On Semiconductor is a three-terminal positive voltage regulator designed for local, on-card voltage regulation. It provides a fixed 12V output and can deliver up to 500mA of current with adequate heatsinking.

 

This device integrates internal current limiting, thermal shutdown circuitry, and safe-area compensation for the internal pass transistor, making it robust under various operating conditions. It requires no external components for its basic operation.

 

The MC78M12CT is suitable for applications requiring stable voltage regulation. Its TO-220 package with through-hole mounting allows for easy integration into circuit boards and provides a pathway for heat dissipation.

 

Key electrical characteristics include a 12V fixed output voltage, a maximum output current of 500mA, and protection features such as over-temperature and short-circuit limiting. The operating temperature range is from 0°C to 125°C.
