LOW DROPOUT REGULATOR, SEMICONDUCTOR DEVICE INCLUDING SAME AND METHOD OF CONTROLLING SAME

原文（中国語）

A low-dropout (LDO) regulator includes a plurality of power transistors connected in parallel between an input node to which an input voltage is applied and an output node, a comparator that compares an output voltage of the output node with a reference voltage and outputs a control signal, a controller that outputs a control code that controls at least some of the plurality of transistors based on the control signal such that an output current equal to an aim current flows through the output node, and a current limit circuit that detects a target current output from a sample transistor connected to the input node and outputs a target code corresponding to the target current. The controller determines a limit code based on the target code and a preset maximum current, and outputs the control code within a range defined by the limit code.
