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. /C0083/C0067/C0072/C0069/C0077/C0065/C0084/C0073/C0067/C0032/C0068/C0073/C0065/C0071/C0082/C0065/C0077 /C0065/C0080/C0080/C0076/C0073/C0067/C0065/C0084/C0073/C0079/C0078/C0083 C A Current Source V– Current Sink Out Linear Ramp Generator Anode Cathode Top View TO-236 (SOT-23) *Short lead #2 to Cathode (lead #3) via circuit board trace.
