Abstract
A linear current regulator is disclosed herein, which comprises a first amplifier, a current converter unit, a first resistor, a reference current source, a regulating unit, and a reference voltage circuit. The current converter unit converts voltage level of an non-inverting input end of the first amplifier into a regulated current and outputs it. The first resistor is coupled to an inverting input end and an output end of the first amplifier. The reference current source is coupled to the inverting input end of the first amplifier and the first resistor. The regulating unit is coupled to the reference current source and outputs a current signal for adjusting a reference current of the reference current source. The reference voltage circuit has at least two input ends. The reference voltage circuit has one input end coupled to a reference voltage and another input end coupled to the first amplifier.
