Abstract
The present technology relates to a voltage supply circuit, and the voltage supply circuit according to the present technology includes a signal generation circuit configured to generate an active mode enable signal according to a chip selection signal provided from an external device, and generate a standby mode enable signal using an external voltage provided from the external device, an active voltage regulator configured to receive the active mode enable signal and output an active mode operation voltage when the active mode enable signal is in a high state, and a standby voltage regulator configured to receive the active mode enable signal and the standby mode enable signal, output a standby mode operation voltage while the standby mode enable signal is in the high state, and output a voltage lower than the standby mode operation voltage when the active mode enable signal is in the high state.
