Description

The L78Lxx 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 L78Lxx series used as

Zener diode/resistor combination replacement,

offers an effective output impedance improvement
