PROBLEM TO BE SOLVED: To provide a stabilized power source circuit having an overcurrent protection circuit wherein output current and output voltage each have 'a chevron-shaped characteristic', without restricting a range of the output voltage. SOLUTION: This stabilized power source circuit having an overcurrent protection function to the output current has: a reference voltage generation part generating a reference voltage; an output part outputting a prescribed constant voltage on the basis of the reference voltage; and an overcurrent detection part detecting the output current from the output part, and detecting overcurrent to the detected output current. The overcurrent detection part reduces the output current and the output voltage from the output part when detecting the overcurrent. COPYRIGHT: (C)2006,JPO&NCIPI
