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.

Features

Standard Application Circuit

●

Output Voltage Range -5 to -24V

Output current up to 1.5A

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.
