TERMINAL NEGATIVE VOLTAGE REGULATORS
The IL7900 series of fixed output negative
voltage regulators are intended as complements to
the IL7800 series devices. These negative regulators
are available in the same seven-voltage options as
the IL7800 devices. In addition, one extra voltage
option commonly employed in MECL systems is also
available in the current series.

2. Ground
3. Output
(H eatsink

to Pin 2.)
Available in fixed output voltage options from -5.0 to -24 volts, 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 ampere.

A common ground is required between the input and
the output voltages. The input voltage must remain
typically 2.0V more negative even during the high
point on the input ripple voltage.
XX - these two digits of the type number indicate
voltage
Cin - is required if regulator is located an appreciable
distance from power supply filter
Co - improves stability and transient response
