Description
The L78L 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 L78L series used as
Zener diode/resistor combination replacement,
offers e improvement along with lower quiescent
current and lower noise.
