IC L7900
The L7900 series of three-terminal negative regulators is available in TO-220, TO-220FP TO-3 and D2PAK 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.
Ciruit Regulator L7900
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.
