DESCRIPTION
SOT-89 PKG
This series of fixed-voltage monolithic integrated-circuit
voltage regulators is designed for a 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. The internal limiting and thermal shutdown
features of these regulators make them essentially
immune to overload. When used as a replacement for a
zener
diode-resistor
combination,
an
effective
improvement in output impedance can be obtained
together with lower-bias current.

LM79LXX
Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible. Thermal
effects must be taken into account separately.
All characteristics are measured with a 0.33uF capacitor across the input and a 0.1uF capacitor across the output.
This specification applies only for DC power dissipation permitted by absolute maximum ratings.
