DESCRIPTION

The SST502 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 device which is extremely

simple to operate.

With nominal current ranges from 0.43 mA to 4.7 mA, the

SST502 series will meet a wide array of design requirements.

The low-cost TO-236 surface-mount package ensures a

cost-effective design solution.
