J507
Current Regulator Diode
Linear Systems replaces discontinued Siliconix J507
The Linear Systems J507 is a ± 20% range current regulator
The J507 is a ±20% range current regulator designed
for demanding applications in test equipment and
instrumentation. The J507 utilizes JFET techniques to
produce a single two-leaded device which is extremely
simple to operate.
