DESCRIPSION
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. Current limiting is include to limit the
peak output current(250mA ~ 300mA) to a safe value.
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.
