摘要： A regulator and a DC/DC converter are provided in which a soft start is carried out even when an output is short-circuited by abnormality. Regulator includes soft start circuit that gradually starts up a reference voltage that is input into error amplifier from 0 V to the reference voltage and soft start reset circuit that monitors an input of error amplifier and performs soft start of soft start circuit again when an output of output terminal Vo is short-circuited. Soft start reset circuit includes comparator that is disposed in parallel with an input of error amplifier, offset voltage that gives an offset to the input of comparator, and NPN transistor that is turned on or off in accordance with a result of comparison of comparator and discharges capacitor C by being turned on when the output is short-circuited.
