DESCRIPTION
The L78L00 series of three-terminal positive
regulators employ internal current limiting and
thermal
shutdown, making
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
