General Description

The TS7900 series of fixed output negative voltage regulators are intended as complements to the popular TS7800

series device. These negative regulators are available in the same seven-voltage options as the TS7800 devices. In

addition, one extra voltage option commonly employed in MECL systems is also available in the negative TS7900 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

heatsinking they can deliver output currents in excess of 1 ampere.

This series is offered in 3-pin TO-220, ITO-220 package.

Features

Standard Application

Output current up to 1A

No external components required

Internal thermal overload protection

Internal short-circuit current limiting

Output transistor safe-area compensation

Output voltage offered in 4% tolerance

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.
