1.0 A Negative Voltage
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.

connected to Pin 2.
Pin 1. Ground
Heatsink surface (shown as terminal 4 in
case outline drawing) is connected to Pin 2.
A common ground is required between the input
and the output voltages. The input voltage must
remain typically 2.0 V above more negative even
during the high point of the input ripple voltage.
XX, These two digits of the type number
indicate nominal voltage.
** Cin is required if regulator is located an
appreciable distance from power supply filter.
** CO improve stability and transient response.
