STMICROELECTRONICS L78L12ACZ Voltage Regulator

The L78L series consists of three-terminal positive voltage regulators with internal current limiting and thermal shutdown, offering output currents up to 100 mA. Available in various fixed voltages including 3.3V, 5V, 6V, 8V, 9V, 10V, 12V, 15V, 18V, and 24V, these regulators require no external components. They feature thermal overload and short-circuit protection, making them suitable for local and on-card regulation, noise reduction, and high-current voltage regulation when combined with power pass elements. Different packages include TO-92, SO-8, and SOT-89, with high environmental compliance options.
