When a circuit requires a stable 5V power supply with relatively high current capability, the MC78T05ACT remains a noteworthy component in many legacy and industrial designs.
This three-terminal positive voltage regulator provides a fixed 5V output and supports output currents of up to 3A. The MC78T05ACT is available in a TO-220 package and features built-in protection mechanisms, including current limiting and thermal protection. The AC version also offers a tighter output-voltage tolerance specification.
