® L7800 SERIES POSITIVE VOLTAGE REGULATORS OUTPUT CURRENT UP TO 1.5 A OUTPUT VOLTAGES OF 5; 5.2; 6; 8; 8.5; 9; 12; 15; 18; 24V www.DataSheet4U.com s THERMAL OVERLOAD PROTECTION s SHORT CIRCUIT PROTECTION s OUTPUT TRANSITION SOA PROTECTION s s DESCRIPTION The L7800 series of three-terminal positive regulators is available in TO-220 ISOWATT220 TO-3 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. 1 2 TO-3 D2PAK TO-220 ISOWATT220 BLOCK DIAGRAM November 1999 1/25 L7800 ABSOLUTE MAXIMUM RATINGS Symbol Vi Io P tot T op T st g www.DataSheet4U.com Parameter DC Input Voltage (for VO = 5 to 18V) (for V O = 20, 24V) Output Current Power Dissipation Operating Junction Temperature Range (for L7800) (for L7800C) Storage Temperature Range Value 35 40 Internally limited Internally limited -55 to 150 0 to 150 -65 to 150 Unit V V o o o C C C THERMAL DATA Symbol Parameter D PAK 3 62.5 2 TO-220 3 50 ISOWATT220 4 60 TO-3 4 35 Unit o o R thj...
