Transcription of Current Regulator Diode - Calogic
1 Current Regulator DiodeJ 500 Series / SST500 SeriesFEATURES Simple Two Lead Current Sources 1 to 100 Volt Operation Zero Temperature Coefficient Simplifies Floating Current Sources No Power Supplies RequiredGENERAL DESCRIPTIONC alogic s Current Regulator Diode is available in plastic TO-92and surface mount SOT-23. The devices are selected fornarrow Current ranges and are excellent choices for testinstrumentation and medical applications. With nominalcurrent ranges from to , all in 20% bands. Thedevices allow the designer a cost effective method ofproviding a Current Regulator with no power supplyrequirements and lower part count. The lower Current devicesoperate at 1 INFORMATIONPart No.
