MC7900 Series
1.0 A 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
