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–
This document provides technical data for the MG7900 (likely a typo in source text) and MC7900 series of three-terminal negative voltage regulators. These devices are intended as complements to the popular MC7800 series and offer fixed output voltages ranging from -5.0 V to -24 V.
The datasheet details maximum ratings, thermal characteristics, and comprehensive electrical specifications for various device types within the series (e.g., MC7905C, MC7912AC). Key features include internal thermal overload protection, short circuit current limiting, and safe-area compensation. The document includes representative schematic diagrams and ordering information for different package suffixes.
