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.

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.
