Part Description: Negative voltage regulators


Part Details:

L79xxC Negative voltage regulators Features Output current up to 1.5 A Output voltages of -5; -8; -12; -15; -20 V Thermal overload protection Short circuit protection Output transition SOA protection TO-220 TO-220FP Description The L79XXC series of three-terminal negative regulators is available in TO-220, TO-220FP 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 D2PAK 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. Table 1.
