L78LxxAB, L78LxxAC, L78LxxC 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% (AC) or ± 8% (C) selection TO-92 Description SO-8 The L78Lxx 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 with power pass elements to make high-current voltage regulators. The L78Lxx series used as Zener diode/resistor combination replacement, offers an effective output impedance improvement Table 1. SOT-89 of typically two orders of magnitude, along with lower quiescent current and lower noise.

Our SO-8 package used for voltage regulators is modified internally to have pins 2, 3, 6 and 7 electrically communed to the die attach flag. This particular frame decreases the total thermal resistance of the package and increases its ability to dissipate power when an appropriate area of copper on the printed circuit board is available for heat-sinking. The external dimensions are the same as for the standard SO-8. Table 3. Symbol RthJC RthJA 1. Thermal data Parameter SO-8 Thermal resistance junction-case. (max) Thermal resistance junction-ambient.
