描述 Description

The L79Lxx series of three-terminal negative

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 oncard 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 L79Lxx 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.
