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.
SCHEMATIC DIAGRAM
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.
