DESCRIPTION
The L78L00 series of three-terminal positive
regulators employ internal current limiting and
thermal shutdown, making them essentially
indestructible. If adequate heatsink is provided,
they can deliver up to 100 mA output current.
They are intended as fixed voltage regulatorsin 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
voltageregulators.
The L78L00 series used as Zener diode/resistor
combination replacement, offers an effective

output impedance improvement of typically two
orders of magnetude, along with lower quiescent
currentand lower noise.

(*) Our SO-8 package used for Voltage Regulators is modified internally to have pins 2, 3, 6 and 7 electrically commoned 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
appropriatearea of copper on the printed circuit boardis available for heatsinking. The external dimensions are the same as forthe standard
SO-8
