Abstract
According to an embodiment, a power source circuit has first, second, and third one-conductivity-type transistors with commonly connected emitters, wherein the first transistor has an emitter area that is N times those of the second and third transistors. The power source circuit outputs a reference voltage that is set by a voltage drop that is caused at a resistance between bases of the first and second transistors and a forward voltage of a PN-junction diode, and outputs a BG_OK signal in response to a potential at a collector of the third transistor.
