L7800 SERIES POSITIVE VOLTAGE REGULATORS s s s s s OUTPUT CURRENT UP TO 1.5 A OUTPUT VOLTAGES OF 5; 5.2; 6; 8; 8.5; 9; 12; 15; 18; 24V THERMAL OVERLOAD PROTECTION SHORT CIRCUIT PROTECTION OUTPUT TRANSITION SOA PROTECTION 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 1 3 D2PAK 3 1 2 1 2 3 TO-220 ISOWATT220 BLOCK DIAGRAM January 1997 1/25 L7800 ABSOLUTE MAXIMUM RATINGS Symbol Vi Io Pt ot To p T stg Parameter DC Input Voltage (for VO = 5 to 18V) (for VO = 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 125 0 to 150 - 40 to 150 o o o Unit V V C C C THERMAL DATA Symbol Parameter D2PAK 3 62.5 TO-220 3 50 ISOWATT220 4 60 TO-3 4 35 Unit o o R t hj- case Thermal Resistance Junction-case Max R th j-a mb Thermal Resistance Junction-ambient Max C/W C/W CONNECTION DIAGRAM AND ORDERING NUMBERS (top view) TO-220 & ISOWATT220 D2PAK TO-3 Type L7805 L7805C L7852C L7806 L7806C L7808 L7808C L7885C L7809C L7812 L7812C L7815 L7815C L7818 L7818C L7820 L7820C L7824 L7824C TO-220 L7805CV L7852CV L7806CV L7808CV L7885CV L7809CV L7812CV L7815CV L7818CV L7820CV L7824CV D PAK (*) L7805CD2T L7852CD2T L7806CD2T L7808CD2T L7885CD2T L7809CD2T L7812CD2T L7815CD2T L7818CD2T L7820CD2T L7824CD2T 2 ISOWATT 220 L7805CP L7852CP L7806CP L7808CP L7885CP L7809CP L7812CP L7815CP L7818CP L7820CP L7824CP TO-3 L7805T L7805CT L7852CT L7806T L7806CT L7808T L7808CT L7885CT L7809CT L7812T L7812CT L7815T L7815CT L7818T L7818CT L7820T L7820CT L7824T L7824CT Output Voltage 5V 5V 5.2V 6V 6V 8V 8V 8.5V 9V 12V 12V 15V 15V 18V 18V 20V 20V 24V 24V (*) AVAILABLE IN TAPE AND REEL WITH ”-TR” SUFFIX 2/25 L7800 APPLICATION CIRCUIT SCHEMATIC DIAGRAM 3/25 L7800 TEST CIRCUITS Figure 1 : DC Parameter Figure 2 : Load Regulation.

C allows a slow risetime of the Vo Figure 32 : Light Controllers (Vo min = Vxx + VBE). VO falls when the light goes up VO rises when the light goes up Figure 33 : Protection against Input Short-circuit with High Capacitance Loads. Application with high capacitance loads and an output voltage greater than 6 volts need an external diode (see fig. 33) to protect the deviceagainst input short circuit. In this case the input voltage falls rapidly while the output voltage decrease slowly. The capacitance dischrges by means of the Base-Emitter junction of the series pass transistor in the regulator. If the energy is sufficently high, the transistor may be destroyed. The external diode by-passes the current from the IC to ground. 20/25 L7800 TO-3 (R) MECHANICAL DATA mm MIN.
