Description

This series of fixed-voltage integrated-circuit voltage regulators of the 78L12 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 of the 78L12 can deliver up to 100 mA of output current. The internal limiting and thermal-shutdown features of these regulators of the 78L12 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.
