Abstract
There is to provide a semiconductor device capable of activating a circuit quickly, operating with a lower power consumption in a steady state, and coping with the dispersion of the elements. The semiconductor device includes an amplifier coupled to a power voltage, to output a voltage based on a reference voltage and a voltage of a negative feedback node, to an output node; and a voltage divider coupled to the output node, to output the divided voltage to the negative feedback node. The voltage divider includes first and second voltage dividing paths with different resistance, a first switching circuit coupled to the first and the second voltage dividing paths, in a dividing ratio adjustable way, and a second switching circuit for controlling the first and the second voltage dividing paths.
