Datasheet
DESCRIPTION
The L7900 series of three-terminal negative
regulators is available in TO-220, ISOWATT220
TO-3 and D
output voltages, making it useful in a wide range
of applications.These regulators can provide local
on-card regulation, eliminating the distribution
problems associated with single point regulation;
furthermore, having the same voltage option 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.
they can deliver over 1.5A output current.
Although designed primarily as fixed voltage
regulators, these devices can be used with
external
voltages and currents.
