The L78Lxx series of three-terminal positive regulators have an output current of 100 mA and output voltages of 3.3, 5, 6, 8, 9, 10, 12, 15, 18, and 24 V.
The L78Lxx series of three-terminal positive regulators employ internal current limiting and thermal shutdown, making them essentially indestructible. They are intended as fixed voltage regulators in a wide range of applications including local or on-card regulation. If adequate heat-sink is provided, they can deliver up to 100 mA output current.
