GENERAL DESCRIPTION
Calogic’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 0.24mA to 4.7mA, 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 volt.
