Description
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 100 mA of output
current. The internal limiting and termal 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.

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 0.33µF capacitor across the input and a 0.1 µF
capacitor across the output.
