DESCRIPTION
The L78L00series 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 100mA output current.They are intended as fixed voltage regulators in a wide range of applications including local or on-card 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 L78L00series used as Zener diode/resistor combination replacement,offers an effective output impedance improvement of typically two
orders of magnitude,along with lower quiescent current and lower noise.

(*)Our SO-8package used for Voltage Regulators is modified internally to have pins 2,3,6and 7electrically 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 appro-priate 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.
