DESCRIPTION
The L78L00 series of three-terminal positive regu-
lators 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 regulators in a wide range of applications in-
cluding 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 volt-
age regulators.
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 current and
lower noise.
