® L7800 SERIES POSITIVE VOLTAGE REGULA TORS 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 THERM AL OVERLOAD PROTECTION s SHORT CIRCUIT PROTECTION s OUTPUT TRANSITION SOA PROT ECTION s s DESCRIPTION The L7800 serie s of three-terminal positive regulators is available in TO-220 ISOWATT220 TO-3 and D2PAK packages and several fixed o utput voltages, making it useful in a w ide range of applications.These regulat ors can provide local on-card regulatio n, eliminating the distribution problem s associated with single point regulati on. Each type employs internal current limiting, thermal shut-dow

n and safe area protection, making it es sentially indestructible. If adequate h eat sinking is provided, they can deliv er over 1A output current. Although des igned primarily as fixed voltage regula tors, these devices can be used with ex ternal components to obtain adjustable voltages and currents. 1 2 TO-3 D2PAK TO-220 ISOWATT220 BLOCK DIAGRAM Nov ember 1999 1/25 L7800 ABSOLUTE MAXIMU M RATINGS Symbol Vi Io P tot T op T st g www.DataSheet4U.com Parameter DC Inp ut Voltage (for VO = 5 to 18V) (for V O = 20, 24V) Output Current Power Dissip ation Operating Junction Temperature Ra nge (for L7800) (for L7800C) Storage Te mperature 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 P AK 3 62.5 2 TO-220 3 50 ISOWATT220 4 60 TO-3 4 35 Unit o o R thj- ca se T hermal Resistance Junction-case Max R t hj- amb Thermal Resistance Junction-amb ient Max C/W C/W CONNECTION DIAGRAM A ND ORDERING NUMBERS (top view) TO-220 & ISOWATT 220 D PAK 2 TO-3 Type L78 05 L7805C L7852C L7806 L7806C L7808 L78 08C L7885C L7809C L7812 L7812C L7815 L7 815C L7818 L7818C L7820 L7820C L7824 L7 824C TO-220 L7805CV L7852CV L7806CV L7 808CV L7885CV L7809CV L7812CV L7815CV L 7818CV L7820CV L7824CV D PAK (*) L7805CD2T L7852CD
