DESCRIPTION  
The L7900A series of three-terminal negative regu-  
lators is available in TO-220 package and with sev-  
eral output voltage. They can provide local on-card  
regulation, eliminating the distribution problems as-  
sociated with single point regulation ; furthermore,  
having the same voltage options as the L7800 posi-  
tive standard series, they are particularly suited for  
split power supplies. In addition, the -5.2V is also  
available for ECL system.  
TO-220  
If adeguate heatsinking is provided, the L7900A  
series can deliver an output current in excess of  
1.5A. Although designed primarly as fixed voltage  
regulators, these devices can be used with external  
components to obtain adjustable voltages and cur-  
rents.
