Description
SO-8
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.
power pass elements to make high-current
voltage regulators.
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
Table 1.
SOT-89
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.
