Abstract
The present invention relates to a voltage stabilizer that stabilizes the voltage of a power supply line on a semiconductor substrate and is intended to provide a voltage stabilizer having a small mounting area on the semiconductor substrate, capable of stabilizing the voltage of the power supply path connecting the power supply and semiconductor substrate. The voltage stabilizer includes a monitoring sectionconnected to the power supply line Vdd that monitors the potential of the power supply line Vdd and outputs a monitor signal indicating the monitoring result and a first current control sectionthat passes a current from the power supply line Vdd according to the monitor signal to stabilize the voltage of the power supply line Vdd, capable of freely passing a current continuously.
