ABSTRACT:
A series regulator circuit that enables detection of a voltage drop and reduces consumed current in a static state. A constant current source, which is connected to a power supply voltage line, is connected to a bipolar transistor. The bipolar transistor includes an emitter terminal and base terminal connected to a ground line via first and second resistors, respectively. The constant current source is connected to the source terminal of a PMOS transistor and the gate terminal of an NMOS transistor. The source terminal of the NMOS transistor is connected via third and fourth resistors to the base terminal of the bipolar transistor.
