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.
