Semiconductor
S79xxPI
Fixed-Negative-Voltage
Regulator
Descriptions
This series of fixed-negative-voltage monolithic integrated-circuit voltage
regulators is designed to complement series S7800 in a wide range of applications. These applications include on-card
regulator for elimination of noise and distribution problems associated with single point regulations. Each of these
regulators can deliver up to 1.0 amperes of output current. The internal current Limiting and thermal shutdown features of these
regulators make them essentially immune to overload. In addition to use as fixed-voltage
regulators, these device can be used with external components to obtain adjustable output voltages and also as the power pass element in precision
regulators.
