Abstract

In this circuit, an external voltage source is supplied or down converted in response to a normal operating mode to provide the internal voltage source of a first level to the internal circuit. The external voltage source is converted to a voltage of a second level, lower than the first level, in response to a low consumption power mode having a complementary relation with the normal mode.
