100mA Negative Voltage Regulator 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.
