Abstract
A semiconductor integrated circuit is provided with a reference voltage generation circuit for generating a voltage to be a reference, a function circuit that is operated using an output voltage of the reference voltage generation circuit, and a reference voltage stabilization capacitor for stabilizing the output voltage, which is connected to an output terminal of the reference voltage generation circuit. During standby, the function circuit stops operating while the reference voltage generation circuit continues operating to prevent discharging of the reference voltage stabilization capacitor, thereby realizing reduction in power consumption of the function circuit such as an analog circuit as well as high-speed recovery from the standby state to the normal operation state.
