The ON Semiconductor MC78T12CT is a three-terminal positive voltage regulator IC designed to drive loads in excess of 3.0 A. It features internal current limiting, thermal shutdown, and safe-area compensation for robust operation.
This device provides a fixed 12V output voltage with a typical output current capability of 3A. It requires no external components for basic regulation. The regulator operates with an input voltage up to 35Vdc (for 5.0V-12V devices) and has a typical voltage dropout of 2.5V at 3A.
Packaged in a TO-220-3 configuration, the MC78T12CT is suitable for through-hole mounting. Its operating temperature range is from 0°C to 125°C, making it suitable for various industrial applications. The device also includes over-current and over-temperature protection features.
This series of regulators can be used with external components to obtain adjustable voltages and currents, or with a series-pass transistor to supply up to 15A at the nominal output voltage.
