description

This series of fixed-voltage 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.

One of these regulators can deliver up to 100 mA

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.
