The MC7900 series of fixed output negative voltage regulators are

intended as complements to the popular MC7800 series devices. These

negative regulators are available in the same seven–voltage options as the

MC7800 devices. In addition, one extra voltage option commonly employed

in MECL systems is also available in the negative MC7900 series.

Available in fixed output voltage options from –5.0 V to –24 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 1.0 A.
