Semiconductor
S78Lxx
Positive-Voltage
Regulators
Descriptions
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, on effective improvement in output impedance can be obtained together with lover-bias current.
