ABSTRACT:
A two-terminal current regulator has a sensing resistor, a reference voltage generator, a current controller, an error amplifier for controlling the current controller such that a voltage drop across the sensing resistor is equalized to a reference voltage generated by the reference voltage generator, and a current distributor for distributing currents to the reference voltage generator, current controller and the error amplifier such that the currents are proportional to a current flowing through the sensing resistor. Thus, a high precision constant current characteristic is attained.
