DESCRIPTION
The L7900series of three-terminal negative regula-
tors is available in TO-220 and TO-3 packages and
with several output voltages. They can provide local
on-cardregulation, eliminating the distribution prob-
lemsassociatedwithsinglepoint regulation; further-
more,havingthesamevoltage optionsasthe L7800
positive standard series, they are particularly suited
for split power supplies. In addition, the –5.2Vis
also available for ECL system.
If adeguate heatsinking is provided, the L7900
series can deliver an output current in excess of
1.5A. Although designed primarly as fixed voltage
regulators, these devices can be usedwith external
components to obtain adjustable voltages and cur-
rents.
