MC79M00

MC79M00 Series 500 mA Negative Voltage Regulators The MC79M00 series of fixed output negative voltage regulators are intended as complements to the popular MC78M00 series devices. Available in fixed output voltage options of −5.0 V, −8.0 V, −12 V and −15 V, these regulators employ current limiting, thermal shutdown, and safe−area compensation, making them remarkably rugged under most operating conditions. With adequate heatsinking they can deliver output currents in excess 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) Package Pb−Free Packages are Available DEVICE TYPE/NOMINAL OUTPUT VOLTAGE Device MC79M05 MC79M08 MC79M12 MC79M15 Nominal Output Voltage −5.0 V −8.0 V −12 V −15 V www.DataSheet4U.com http://onsemi.com THREE−TERMINAL NEGATIVE FIXED VOLTAGE REGULATORS STANDARD APPLICATION Input Cin* 0.33 mF MC79MXX Output CO** 1.0 mF A common ground is required between the input and the output voltages. The input voltage must remain typically 1.1 V more negative even during the high point of the input ripple voltage. XX These two digits of the type number indicate nominal voltage. * Cin is required if regulator is located an appreciable distance from power supply filter. ** CO improve stability and transient response.
