DESCRIPTION
The L78L00 series of three-terminal positive regulators employ internal current limiting and thermal shutdown, making them essen tially indestructible. If adequate heat-sink is provided, they can deliverup to 100 mA output current. T hey are i nte nded as fixed volt age regulators in a wide range of applications including local or on-card regulation for elimination of noise and distribution problems associated with single-poi nt regulation. In addition, they c an be used with power pass elements to make high-current voltage regulators. The L78L00 series used as Zener diode/resistor combination replacement, offers an effective output impedanc e improvement of typically t wo
orders of magnitude, along with lower quiescent current and lower noise.

ABSOLUTE MAXIMUM RATINGS
(*) 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 a n appro­priate area of copper on the printed circuit board is available for heat-sinking. The external dimensions are the same as forthestandard SO-8.
