STMICROELECTRONICS L78M05CV Voltage Regulator

The L78M series of fixed voltage regulators are three-terminal positive devices available in various packages, including TO-220, TO-220FP, DPAK, and IPAK. They provide output voltages from 5V to 24V with current capacity up to 0.5A, accompanied by internal current limiting, thermal shutdown, and safe area protection, making them highly durable. These regulators excel in local regulation, simplifying design while offering guaranteed performance over extended temperature ranges. They are ideal for power supply systems requiring stable, reliable voltage regulation with thermal and short-circuit protections.
