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 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 L78L00 series used as Zener diode/resistor

combination replacement, offers an effective

output impedance improvement of typically two

SO-8

SOT-89

orders of magnitude, along with lower quiescent

current and lower noise.
