The L79L00 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 L79L00 series used as Zener diode/resistor combination replacement, offers an effective
output impedance improvement of typically two orders of magnitude, along with lower quiescent
current and lower noise.
