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.

If adequate heatsink is provided, they can deliver up to 100 mA output current. They are intended as fixed voltage regulators in a wide range of applications including local or on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power pass elements to make high-current voltage regulators. The L78L00 series used as Zener diode/resistor combination replacement, offers an effective output impedance improvement of typically two orders of magnetude, along with lower quiescent current and lower noise.

OUTPUT CURRENT TO 0.5A OUTPUT VOLTAGES OF 5; 6; 8; 9; 10; 12; 15; 18; 20; 24V THERMAL OVERLOAD PROTECTION SHORT CIRCUIT PROTECTION OUTPUT TRANSISTOR SOA PROTECTION DESCRIPTION The L78M00 series of three-terminal positive regulators is available in TO-220, ISOWATT220, SOT-82, SOT-194 and DPAK packages and with 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 0.5A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. 3 1 SOT-82 TO-220 SOT-194 DPAK (TO-252) ISOWATT220 BLOCK DIAGRAM April 1994 1/19 L78M00 SERIES ABSOLUTE MAXIMUM RATINGS Symbol Parameter Value Unit 35 40 V V Vi DC Input Voltage (for V o = 5 to 18V) (for V o = 20, 24V) Io Output Current Internally limited Internally limited Ptot Power Dissipation T stg Storage Temperature Top Operating Junction Temperature - 65 to + 150 C 0 to + 150 C THERMAL DATA Symbol Parameter Rthj-case Thermal Resistance Junction-case Rthj-amb Thermal Resistance Junction-ambient Max Max SOT-82 SOT-194 DPAK TO-220 ISOWATT220 8 100 3 50 4 60 Unit o C/W C/W o CONNECTION DIAGRAM AND ORDERING NUMBERS (top view) TO-220/ISOWATT22 0 SOT82/194 DPAK Order Code Output Voltage TO-220 ISOWATT220 SOT-82 SOT-194 DPAK L78M05CV L78M06CV L78M08CV L78M09CV L78M10CV L78M12CV L78M15CV L78M18CV L78M20CV L78M24CV L78M05CP L78M06CP L78M08CP L78M09CP L78M10CP L78M12CP L78M15CP L78M18CP L78M20CP L78M24CP L78M05CX L78M06CX L78M08CX L78M09CX L78M10CX L78M12CX L78M15CX L78M18CX L78M20CX L78M24CX L78M05CS L78M06CS L78M08CS L78M09CS L78M10CS L78M12CS L78M15CS L78M18CS L78M20CS L78M24CS L78M05CDT L78M06CDT L78M08CDT L78M09CDT L78M10CDT L78M12CDT L78M15CDT L78M18CDT L78M20CDT L78M24CDT 2/19 5V 6V 8V 9V 10V 12V 15V 18V 20V 24V L78M00 SERIES APPLICATION CIRCUIT SCHEMATIC DIAGRAM 3/19 L78M00 SERIES TEST CIRCUITS Figure 1 : DC Parameters.

OUTPUT CURRENT TO 2A OUTPUT VOLTAGES OF 5 ; 7.5 ; 9 ; 10 ; 12 ; 15 ; 18 ; 24V THERMAL OVERLOAD PROTECTION SHORT CIRCUIT PROTECTION OUTPUT TRANSISTOR SOA PROTECTION DESCRIPTION The L78S00 series of three-terminal positive regulators is available in TO-220 and TO-3 packages and with 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 2A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

VO falls when the light goes up Figure 33 : Protection against Input Short-circuit with High Capacitance Loads. Applications with high capacitance loads and an output voltage greater than 6 volts need an external diode (see fig. 33) to protect the device against input short circuit. In this case the input voltage falls rapidly while the output voltage decreases showly. The capacitance discharges by means of the BaseEmitter junction of the series pass transistor in the regulator. If the energy is sufficiently high, the transistor may be destroyed. The external diode bypasses the current from the IC to ground. 18/21 VO rises when the light goes up L78S00 SERIES TO-3 MECHANICAL DATA mm DIM. MIN. inch TYP. MAX. MIN. TYP. MAX.

They can provide local on-card regulation, eliminating the distribution problems associated with single point regulation; furthermore, having the same voltage options as the L7800 positive standard series, they are particularly suited for split power supplies. In addition, the -5.2V is also available for ECL system. If adeguate heatsinking is provided, the L7900 series can deliver an output current in excess of 1.5A. Although designed primarly as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

For value given, capacitor must be solid tantalum. If aluminium electrolitics are used, at least ten times value should be selected. C 1 is required if regulator is located an appreciable distance from power supply filter. To improve transient response. If large capacitors are used, a high current diode from input to output (1N4001 or similar) should be introduced to protect the device from momentary input short circuit.

OUTPUT CURRENT UP TO 100 mA OUTPUT VOLTAGES OF -5; -6; -8; -9; -12; -15V THERMAL OVERLOAD PROTECTION SHORT CIRCUIT PROTECTION NO EXTERNAL COMPONENTS ARE REQUIRED AVAILABLE IN EITHER 5% (AC) OR 10% (C) SELECTION DESCRIPTION The L79L00 series of three-terminal negative regulators employ internal current limiting and thermal shutdown, making them essentially indestructible. If adequate heatsink is provided, they can deliver up to 100 mA output current. They are intended as fixed voltage regulators in a wide range of applications including local or on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power pass elements to make high-current voltage regulators. The L79L00 series used as Zener diode/resistor combination replacement, offers an effective output impedance improvement of typically two orders of magnetude, along with lower quiescent current and lower noise.

This particular frame decreases the total thermal resistance of the package and increases its ability to dissipate power when an appropriate area of copper on the printed circuit board is available for heatsinking.
