1 DATA Semiconductor Components Industries, LLC, 2016 November, 2021 Rev. 291 Publication Order Number: MC78M00 /D500 mA Positive VoltageRegulatorsMC78M00, MC78M00A,NCV78M00 SeriesDescriptionThe MC78M00 /MC78M00A Series Positive Voltage Regulators areidentical to the popular MC7800 Series devices, except that they arespecified for only half the output current . Like the MC7800 devices,the MC78M00 three terminal Regulators are intended for local,on card Voltage current limiting, thermal shutdown circuitry and safe areacompensation for the internal pass transistor combine to make thesedevices remarkably rugged under most operating output current , with adequate heatsinking is 500 No External Components Required Internal Thermal Overload Protection Internal Short Circuit current Limiting Output Transistor Safe Area Compensation MC78M00A High Accuracy ( 2%)Available for V, V, 12 V and 15 V NCV Prefix for Automotive and Other Applications RequiringUnique Site and Control Change Requirements; AEC Q100 Qualified and PPAP Capable These are Pb Free DevicesFigure 1.
