Product Summary

DESCRIPTION:The L7900 series of three-terminal negative regulators is available in TO-220, ISOWATT220 TO-3 and D2 PAK packages and several fixed
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. If adequate heat sinking is provided,
they can deliver over 1.5A output current. Although designed primarily as fixed voltage regulators, these devices can be used with
external components to obtain adjustable voltages and currents
