STUDY OF HIGH-STABILITY CURRENT REGULATORS FOR CURRENT FROM 0.1A TO 8A

Improving the temperature stability and widening the constant current range are two important problems to be solved in the application of the current regulators. This paper introduces a modular approach for the design of the current regulator with a very wide current range. The test results show that their output current ranges from 0.1A to 8A, with its current temperature coefficient as low as 10-4/℃ to 10-5/℃ and limiting voltage lower than 0.4V.
