DESCRIPTION
The L78L00 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 deliverup 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 L78L00 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.
