| Semiconductor S79xxPIC 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. Features * Output Current UP to 1.0A * Internal Thermal Overload Protection * Internal Short-Circuit Current Limiting * No External Components * Output Transistor Safe-Area Compensations Ordering Information Type NO.
