General Description
The TS7900B series of fixed output negative voltage regulators are intended as complements to the popular
TS7800B series device. These negative regulators are available in the same seven-voltage options as the TS7900B
devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative
TS7900B 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.

TS79xxBCM RN
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.
