元器件交易网www.cecb2b.comThree-Terminal Voltage RegulatorsNegativeThe MC79M00 series of fixed output negative voltage regulators areintended as complements to the popular MC78M00 series devices.Available in fixed output voltage options of –5.0, –8.0, –12 and –15 V,these regulators employ current limiting, thermal shutdown, and safe–areacompensation – making them remarkably rugged under most operatingconditions. With adequate heatsinking they can deliver output currents inexcess of 0.5 A.•No External Components Required•Internal Thermal Overload Protection•Internal Short Circuit Current Limiting•Output Transistor Safe–Area Compensation•Also Available in Surface Mount DPAK (DT) PackageDEVICE TYPE/NOMINAL OUTPUT VOLTAGEMC79M05–5.0 VMC79M12–12 VMC79M08–8.0 VMC79M15–15 VORDERING INFORMATIONOutputVoltageOperatingDeviceToleranceTemperature RangePackageMC79MXXBDT, BDT–1DPAKMC79MXXBTTJ = –=–40° to +125to+125°CPlastic PowerMC79MXXCDT, CDT–14.0%40%DPAKMC79MXXCTTJ = 0=0° to +125to+125°CPlastic PowerXX indicates nominal voltage.Representative Schematic DiagramGndkk 4.k0.k2 2 70k ..425.51121k 67.3454.0 kR1k 9.4kkkk 2200...1112R210 kVO20 pF10 pF10 k2.0 k20 k20 k2401.1 k1000.3750VThis device contains 31 active transistors.IMOTOROLA ANALOG IC DEVICE DATAOrder this document by MC79M00/DMC79M00SeriesTHREE–TERMINALNEGATIVE FIXEDVOLTAGE REGULATORST SUFFIXPLASTIC PACKAGECASE 221AHeatsink surfaceconnected to Pin 2.12Pin1.Ground32.Input3.Output11323DT SUFFIXDT–1 SUFFIXPLASTIC PACKAGEPLASTIC PACKAGECASE 369ACASE 369(DPAK)(DPAK)Heatsink surface (shown as terminal 4 incase outline drawing) is connected to Pin 2.STANDARD APPLICATIONInputMC79MXXOutputCC0.33 µin*FO**1.0 µFA common ground is required between the inputand the output voltages.
