Description
The L78L 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
distribution problems associated with single-point
regulation. In addition, they can be used with
power pass elements to make high-current
voltage regulators. The L78L series used as
Zener diode/resistor combination replacement,
offers e improvement along with lower quiescent
current and lower noise.

Notes:
(1)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 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.
