| current regulator diode j 500 s eries / SST500 s eries features simple two lead current sources 1 to 100 volt operation zero temperature coefficient simplifies floating current sources no power supplies required general description calogics current regulator diode is available in plastic to-92 and surface mount sot-23. the devices are selected for narrow current ranges and are excellent choices for test instrumentation and medical applications. with nom inal current ranges from 0.24ma to 4.7ma, all in 20% bands. the devices allow the designer a cost effective method of providing a current regulator with no power supply requirements and lower part count. the lower current devices operate at 1 volt. ordering information part no. package part no. package i f (ma) j500to-92SST500sot-230.24 j501to-92sst501sot-230.33 j502to-92sst502sot-230.43 j503to-92sst503sot-230.56 j504to-92sst504sot-230.75 j505to-92sst505sot-231.00 j506to-92sst506sot-231.40 j507to-92sst507sot-231.80 j508to-92sst508sot-232.40 j509to-92sst509sot-233.00 j510to-92sst510sot-233.60 j511to-92sst511sot-234.70 llc pin configuration to-92 12 bottom view 1 anode 2 cathode sot-23 1 2 3 top view 1 anode 2 cathode product marking (sot-23) SST500 500 sst501 501 sst502 502 sst503 503 sst504 504 sst505 505 sst506 506 sst507 507 sst508 508 sst509 509 sst510 510 sst511 511 5010 externally connect pin 1 to pin2. 3 anode 2 cathode
