SI79XXA
Elektronische Bauelemente
3-Terminal
Negative Voltage Regulator
D e s c r ip t i o n
The SI79XXA series of fixed-voltage monolithic intergratedcircuit voltage regulators designed to complement Series SI78XXA in a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. Each of these regulators can deliver up to 1.5A 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, thesedevices can be used with external components to obtain adjustable output voltage and current and also as the power pass element in precision regulators.
