IL78XXC SERIES THREE-TERMINAL POSITIVE VOLTAGE REGULATORS TO-220 AB These voltage regulators are monolithic integrated circuits designed fixed-voltage regulators for a wide variety of applications including local, on card regulation. These regulators employ internal Pin 1. I nput (H eatsink current limiting, thermal shutdown, and safe-area 2. Ground surface connected 3. Output to Pin 2.) compensation. With adequate heatsinking they can deliver output currents in excess of 1.0 ampere. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. • Output Current in Excess of 1.0 Ampere Standard application • No External Components Required Vout Vin • Internal Thermal Overload Protection I L 78XX • Internal Short - Circuit Current Limiting Ñ Ñ • Output Transistor Safe-Area Compensation 0.1µF 0.33µF • Output Voltage Offered in 2% and 4% Tolerance in Device type/nominal output voltage IL7806 5V IL7812 IL7806 6V IL7815 IL7808 8V IL7818 IL7809 9V IL7824 12 V 15 V 18 V 24 V ** o * A common ground is required between the input and the output voltage.
