ABSTRACT:
The present invention provides a voltage regulator capable of causing a large output current to flow during a heavy load operation, and of making a leakage current from output transistors small during a light load operation. The voltage regulator includes a plurality of output transistors and a circuit for changing connection of the output transistors to allow a W/L value of the output transistor to be changed. Moreover, the voltage regulator further includes an output current detection circuit for detecting an output current, and a circuit for changing connection of the output transistors based on the output current to allow a W/L value of the output transistors to be changed based on the output current.
