Negative voltage regulators
Datasheet - production data
Description
The L79L 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 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 L79L 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.
