General Description

The TS79M00 series of fixed output negative voltage regulators are intended as complements to the popular

TS78M00 series device. These negative regulators are available in the same seven-voltage options as the TS7900

devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative

TS79M00 Series. 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 heat sinking they can deliver output currents in excess of 0.5 ampere.

Note: Follow the derating curve

A common ground is required between the input and the

output voltages. The input voltage must remain typically

2.0V above the output voltage even during the low 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 is not needed for stability; however, it does improve

transient response.
