S79xxPI Semiconductor 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 devices can be used with external components to obtain adjustable output voltages and also as the power pass element in precision regulators. Features • Output Current of 1A • Thermal Shutdown Protection • Short-Circuit Current Limit Protection • No External Components • Output Transistor Safe Operating Area Protection Ordering Information Type NO.
