GENERAL DESCRIPTI ON
Calogic’s cur rent 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, a ll in 20% bands. The
devices allow the designer a cost effective method of
providing a current regulator with no power supply
requirements and lo wer part count. The low er cur ren t de vice s
operate at 1 volt.

Notes: 1. Pulse test - steady state currents may vary.
2. Pulse test - steady state impedances may vary.
3. Min VF required to insure IF > 0.8 IF(MIN).
4. Max VF where IF > 1.1 IF(MAX) is guaranteed.
