1 Semiconductor Components Industries, LLC, 1999 October, 2016 Rev. 181 Publication Order Number: MC78L00A /DMC78L00A series ,NCV78L00A100 mA Positive VoltageRegulatorsThe MC78L00A series of Positive Voltage Regulators areinexpensive, easy to use devices suitable for a multitude ofapplications that require a regulated supply of up to 100 mA. Liketheir higher powered MC7800 and MC78M00 series cousins, theseregulators feature internal current limiting and thermal shutdownmaking them remarkably rugged. No external components arerequired with the MC78L00 devices in many devices offer a substantial performance advantage over thetraditional zener diode resistor combination, as output impedanceand quiescent current are substantially Wide Range of Available, Fixed Output Voltages Low Cost Internal Short Circuit Current Limiting Internal Thermal Overload Protection No External Components Required Complementary Negative Regulators Offered (MC79L00A series ) 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.

10 Internal Short Circuit Protection limitsthe maximum current the circuit will many low current applications, compensationcapacitors are not required. However, it is recommendedthat the regulator input be bypassed with a capacitor if theregulator is connected to the power supply filter with longwire lengths, or if the output load capacitance is large. Theinput bypass capacitor should be selected to provide goodhigh frequency characteristics to insure stable operationunder all load conditions. A mF or larger tantalum,mylar, or other capacitor having low internal impedance athigh frequencies should be chosen. The bypass capacitorshould be mounted with the shortest possible leads directlyacross the Regulators input terminals. Good constructiontechniques should be used to minimize ground loops andlead resistance drops since the regulator has no externalsense lead. Bypassing the output is also 9. Current RegulatorFigure 10.
