DESCRIPTION

The L7900 series 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-card regulation, eliminating the distribution prob-

lems associated with singlepoint regulation; further-

more, having the same voltage options as the L7800

positive standard series, they are particularly suited

for split power supplies. In addition, the –5.2V is

also available for ECL system.

TO-3

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 used with external

components to obtain adjustable voltages and cur-

rents.
