DESCRIPTION
The J500 series is a family of "20% range current regulators
designed for demanding applications in test equipment and
instrumentation. These devices utilize the JFET techniques to
produce a single two-leaded device which is extremely simple
to operate.

Notes:
a. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
b. Max VF where IF = 1.1 IF(max) is guaranteed.
c. Pulse test—steady state currents may vary.
d. Pulse test—steady state impedances may vary.
e. Min VF required to insure IF = 0.8 IF(min).
