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

Available in 2% Voltage Tolerance (See Ordering Information)

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.
