Abstract
PURPOSE: To make the promotion of low power consumption, simultaneously to obtain a stabilized voltage where a supply voltage is dropped to a low level in a manner of absolute value, by applying a control voltage constructed by an intermittently operating output voltage detecting circuit, to the gate, with the supply voltage applied to the drain.
CONSTITUTION: A voltage comparator circuit 1 forms a comparison output, where an output voltage OUT is likely to coincide with the reference voltage Vref, to apply it to the gate of MISFETQ1. By making the reference voltage to a constant voltage, a voltage, made into a constant voltage, can be obtained. Said comparator circuit 1, though with a gate control voltage VG of the MISFETQ1 being formed only intermittently by a clock drive operation, makes a constant voltage output operation of the Q1 by utilizing the level holding action of a gate capacitance C1. In this way, with the source side of the MISFET being the output with a negative feed- back provided as well, the output impedance can be made small and a reduction of the power consumption can be promoted.
