DESCRIPTION
The L78L00 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 on-card regulation for elimination of noise and d istribution problems associated with single-point reg ulation. In addition, they can be used with power pass elements to make high-current voltage regulators. The L78L00 series used as Zener diod e/resistor combination replacement, offers an effective output impedance improvement of typically two
TO-92
SOT-89SO-8
orders of magnitude, along with lower quiescent current and lower noise.

(*) Our SO -8 package used for Volta ge Regulators is modifi ed i nt ernally to have pins 2, 3, 6 and 7 el ectrically commune d 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.
