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 lo w er cur ren t de vice s
operate at 1 volt.
