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.
