REGULATOR WITH SOFT-START USING CURRENT SOURCE

摘要

There is provided a regulator with soft-start using a current source. The regulator with soft-start may include: a power switch unit including first and second power switches connected between a power supply terminal and an output terminal; a load capacitor connected between the output terminal and a ground; a voltage detection unit detecting a voltage of the output terminal; a comparison unit comparing a detection voltage and a predetermined reference voltage, and outputting first and second switching signals; a current generating a predetermined constant current; a current control unit switching a connection between a control terminal of the first power switch and the current source unit according to the first switching, and switching a connection between the control terminal of the first power switch and the ground according to the second switching signal; and an error amplification unit amplifying an error voltage between the detection.
