Abstract
The voltage stabilizer for stabilizing a voltage of a circuit includes a first resistor, a second resistor, a voltage controller, and a current supply unit. The voltage controller keeps a voltage of the first resistor constant. The current supply unit supplies a first current to between the first resistor and the second resistor when a second current in the circuit becomes equal to or larger than a predetermined value.
