DESCRIPTION

The J500 series is a family of

"20% range current regulators

designed for demanding applications in test equipment and

instrumentation. These devices utilize the JFET techniques to

produce a single two-leaded device which is extremely simple

to operate.

With nominal current ranges from 0.24 mA to 4.7 mA, the J500

series will meet a wide array of design requirements.

The low-cost TO-226A package ensures a cost-effective

design solution.
