Current Regulator Diode LLC J 500 Series / SST500 Series FEATURES • Simple Two Lead Current Sources to 100 Volt Operation • 1Zero • Temperature Coefficient • Simplifies Floating Current Sources • No Power Supplies Required GENERAL DESCRIPTION Calogic’s 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 nominal 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.
