1 / 24 page December 2007 Rev 14 1/24 24 L79xxC Negative voltage regulators Features ■ Output current up to 1.5 A ■ Output voltages of -5; -6; -8; -12; -15; -18; -20; -24V ■ Thermal overload protection ■ Short circuit protection ■ Output transition SOA protection Description The L79XXC 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 L78XX positive standard series, they are particularly suited for split power supplies. If adequate heat sinking is provided, they can deliver over 1.5 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. TO-220FP D2PAK TO-220 TO-3 Table 1.
