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 http://onsemi.com and −15 V, these regulators employ current limiting, thermal shutdown, and safe−area compensation, making them remarkably THREE−TERMINAL rugged under most operating conditions. With adequate heatsinking NEGATIVE FIXED they can deliver output currents in excess of 0.5 A. VOLTAGE REGULATORS Features • STANDARD APPLICATION No External Components Required • Internal Thermal Overload Protection Input MC79MXX Output • Internal Short Circuit Current Limiting Cin* CO** • Output Transistor Safe−Area Compensation 0.33 (cid:2)F 1.0 (cid:2)F • Also Available in Surface Mount DPAK (DT) Package • A common ground is required between the input Pb−Free Packages are Available 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. DEVICE TYPE/NOMINAL OUTPUT VOLTAGE XXThese two digits of the type number indicate Device Nominal Output Voltage nominal voltage. * Cin is required if regulator is located an MC79M05 −5.0 V appreciable distance from power supply filter.
