SI79XXA  
3-Terminal  
Elektronische Bauelemente  
Negative Voltage Regulator  
Description  
TO-251  
The SI79XXA series of fixed-voltage monolithic intergrated-  
circuit 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.
