100mA Negative Voltage Regulator
LM79LXX
Description
The Bay Linear LM79LXX is integrated linear negative
regulator with three terminals. The LM79LXX offer several
fixed output voltages making them useful in wide range of
applications. These applications include 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.
Each of these regulators can deliver up to 100mA of output
current.
When used in replacement for a Zener diode-resistor
combination, an effective improvement in output impedance
can be obtained together with lower-bias current.
The LM79LXX is available in the plastic TO-92 (Z) package.
