Abstract
A series regulator circuit for reducing current consumption, enabling switching between different current consumption modes, and suppressing output voltage fluctuations. A constant current source, connected to an input voltage line, is connected to a ground voltage line via a resistor elementand transistor B. Gate terminals of transistors M, Mare connected between the constant current sourceand transistor B. The transistor Mis connected to the input voltage line via a transistor Mactivated in a high current mode. The source terminals of the transistors M, Mfunction as the series regulator circuit output terminal, which is connected to the ground voltage line via a resistor elementand transistor M, activated in a high current mode, or via resistor elements. A connection node between the resistor elementsis connected to a base voltage of the transistor B
