January 2007 Rev. 11 1/28 L7800AB/AC series Precision 1A regulators Feature summary ■ Output current in excess of 1A ■ 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, TO-220FP , and D 2PAK 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 problem 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 voltage and currents.
