Order this document by MC7900/D Three-Terminal Negative Voltage Regulators 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. • No External Components Required MC7900 Series THREE–TERMINAL NEG [ ... ]
