Part Description: 2 % negative voltage regulators


Part Details:

L79xxAC 2 % negative voltage regulators Features Output current to 1.5 A Output voltages of -5; -12; -15 V Thermal overload protection Short circuit protection Output transition SOA protection Description TO-220 D2PAK The L79xxAC series of three-terminal negative regulators is available in TO-220 and D2PAK packages and several fixed output voltages. 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 L78xxA 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.
