NIKO-SEM Three-Terminal Positive-Voltage Regulator FEATURES L78L15 GENERAL DESCRIPTION This Series of fixed- voltage monolithic integrated circuit voltage regulators is designed for a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with singlepoint regulation. In addition, they can be used with power-pass elements to make high-current voltage regulators. One of these regulators can deliver up to 100 mA of output current. The internal limiting and thermal shutdown features of these regulators male them essentially immune to overload. When used as a replacement for a zener diode- resistor combination, an effective improvement in output impedance can be obtain -ed together with lower-bias current. l 3-terminal regulators l Output current up to 100 mA l No external component l Internal thermal overload protection l Internal short-circuit current limiting APPLICATIONS l Linear regulator l Instrumentation l Switching power supplies l PCs, Industrial equipment PIN CONFIGURAT IONS DEVICE SELECTION GUIDE Device Package Marking L78L15N TO-92 78L15 1 MAR-14- 2002 NIKO-SEM Three-Terminal Positive-Voltage Regulator L78L15 ABSOLUTE MAXIMUM RATINGS PARAMETER Input Voltage - V I Continuous total power dissipation Storage Temperature Range - TSTG Junction Temperature - TJ Lead Temperature (Soldering, 10 Seconds) - TL VALUE 30V (See Note 1) -55 to +150 °C 125 °C 260 °C Note1: To avoid exceeding the design maximum virtual junction temperature, three ratings should not be exceeded. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation. DISSIPATION RATING TABLE 1 – FREE-AIR TEMPERATURE PACKAGE TO-92 TA ≤ 25°C POWER RATING 650 mW DERATING FACTOR 6.2 mW/°C DERATING ABOVE TA 25 °C TA = 70°C POWER RATING 350 mW † The TO-92 package dissipation rating is based on thermal resistance θJA measured in still air with the device mounted in an Augat socket. The bottom of the package is 10mm (0.375 in) above the stock. DISSIPATION RATING TABLE 2 – CASE TEMPERATURE PACKAGE TO-92 TA ≤ 25°C POWER RATING 1600 mW DERATING FACTOR 28.6 mW/°C DERATING ABOVE TC 94 °C TC = 125°C POWER RATING 713 mW RECOMMENDED OPERATING CONDITIONS PARAMETER Input Voltage - V I L78L15 Output Current - IOUT Operating Virtual Junction Temperature - TJ VALUE 17.5V to 30V 100 mA (Max) 0 to 125 °C 2 MAR-14- 2002 NIKO-SEM Three-Terminal Positive-Voltage Regulator L78L15 ELECTRICAL SPECIFICATIONS (L78L15) ( V I = 23V, IO = 40 mA, CI = 0.33 µF, CO = 0.1 µF, 0 °C < TJ < +125 °C unless otherwise noted.)
