Datasheet - L78L - Positive voltage regulators

1 TO-92 SO-8 SOT-89 Features Output current up to 100 mA Output voltages of ; 5; 6; 8; 9; 10; 12; 15; 18; 24 V thermal overloadprotection Short-circuit protection No external components are required Available in either 4% (A) or 8% (C) selectionDescriptionThe L78L series of three-terminal Positive regulators employ internal current limitingand thermal shutdown, making them essentially indestructible. If adequate heat-sinkis provided, they can deliver up to 100 mA output current . They are intendedas fixed voltage regulators in a wide range of applications including local or on-card regulation for elimination of noise and distribution problems associated withsingle-point regulation. In addition, they can be used with power pass elements tomake high- current voltage regulators .

3 Our SO-8 package used for voltage regulators is modified internally to have pins 2, 3, 6 and 7 electricallycommuned to the die attach flag. This particular frame decreases the total thermal resistance of thepackage and increases its ability to dissipate power when an appropriate area of copper on the printedcircuit board is available for heat-sinking. The external dimensions are the same as for the standard SO-8. Table 2.
