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.
