L7900 SERIES NEGATIVE VOLTAGE REGULATORS s OUTPUT CURRENT UP TO 1.5A s OUTPUT VOLTAGES OF -5; -5.2; -6; -8; -9; -12; -15; -18; -20; -22; -24V s THERMAL OVERLOAD PROTECTION s SHORT CIRCUIT PROTECTION s OUTPUT TRANSITION SOA PROTECTION DESCRIPTION TO-220 TO-220FP 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 D2PAK TO-3 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.
