DESCRIPTION

The L7900 series with three terminals negative
regulators is available in TO-220, ISOWATT220
TO-3 and D2PAK packages and various fixed ones
output voltages, making it usable in a wide range
of applications. These supervisors can bid locally
card scheme, eliminating distribution
problems associated with single-point regulation;
additionally with the same voltage option as
the L7800 positive standard series, that's what they are
particularly suitable for split power supplies. In
Moreover, the -5.2V is also available for ECL
system. If sufficient heat dissipation is provided,
they can provide more than 1.5 A output current.
Although primarily designed as a fixed voltage
regulators, these devices can be used with
external components to get adjustable
voltages and currents.
