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
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 heat sinking they can deliver output currents in excess of 1 ampere.
Features
● Output Voltage: -5 & -12V
● 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.
