ABSTRACT:
A stabilized DC power supply circuit comprises an error amplifier circuit, an output amplifier circuit, an output voltage division circuit, and a reference voltage circuit. A bias current boost circuit capable of stabilized operation is added to the DC power supply circuit. Since the feedback loop of the bias current boost circuit is provided with a hysteresis function or an artificial hysteresis function by a large delay element, it is possible to adaptively control bias current without sacrifice of stability and realize a stabilized DC power supply circuit exhibiting high response and high stability with low current consumption.
