L78L Positive voltage regulators Datasheet - production data Features  Output current up to 100 mA  Output voltages of 3.3; 5; 6; 8; 9; 10; 12; 15; 18; 24 V thermal overload protection  Short-circuit protection  No external components are required  Available in either ± 4% (A) or ± 8% (C) selection Description The L78L series of three-terminal positive regulators employ internal current limiting and thermal shutdown, making them essentially indestructible. If adequate heat-sink is provided, they can deliver up to 100 mA output current. They are intended as fixed voltage regulators in a wide range of applications including local or oncard regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used [ ... ]
