Abstract
A linear power supply device includes a first mirror transistor configured to be capable of generating a first mirror current; a second mirror transistor configured to be capable of generating a second mirror current; a switch circuit that switches between outputting the first mirror current from a current transmission/reception terminal to outside, and receiving external mirror current from outside through the current transmission/reception terminal, on the basis of a switching signal; and a comparison unit that compares the external mirror current with the second mirror current, and draws out current from a second node connected to a first feedback resistor and a second feedback resistor, or injects current into the second node, on the basis of the comparison result.
