Order this document by MC79M00/D 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, –8.0, –12 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 • • • • THREE–TERMINAL NEGATIVE FIXED VOLTAGE REGULATORS Internal Thermal Overload Protection Internal Short Circuit Current Limiting T SUFFIX PLASTIC PACKAGE CASE 221A Output Transistor Safe–Area Compensation Also Available in Surface Mount DPAK (DT) Package Heatsink surface connected to Pin 2.

VI 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.
