ABSTRACT:
A semiconductor integrated circuit with stabilizing capacity has a voltage drop circuit that drops a power supply voltage to a first voltage Vcc1and supplies the Vcc1to a plurality of function blocks; a stabilizing capacity that stabilizes the Vcc1; and a plurality of voltage switching circuits each of which is provided in each of the function blocks and selectively switches between the Vcc1and a base voltage Vss to produce a second voltage Vcc2and supplies the Vcc2to each function block, and each of the function blocks forms a capacity for stabilizing an output of the voltage drop circuit by means of its semiconductor structure by the Vcc1and the Vcc2applied thereto.
