简  介: L7800AB/AC SERIES PRECISION 1A REGULATORS s s s s s s OUTPUT CURRENT IN EXCESS OF 1 A OUTPUT VOLTAGES OF 5; 6; 8; 9; 12; 15; 18; 20; 24V THERMAL OVERLOAD PROTECTION OUTPUT TRANSITION SOA PROTECTION 2% OUTPUT VOLTAGE TOLERANCE GUARANTEED IN EXTENDED TEMPERATURE RANGE DESCRIPTION The L7800A series of three-terminal positive regulators is available in TO-220 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. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.
