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 TS7900 devices. In
addition, one extra voltage option commonly employed in MECL systems is also available in the negative TS7900A
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 1 ampere.
This series is offered in 3-pin TO-220, ITO-220 & TO-263 package.
Features
● Output Voltage Range -5 to -24V
● 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

Standard Application Circuit
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.
