PURPOSE: A voltage stabilizing power system is provided, in which an input terminal and an output terminal are electrically insulated, to thereby stabilize power, avoid response delay caused due to feedback and eliminate loading effect and electric noise. CONSTITUTION: A voltage stabilizing power system comprises a reference voltage generating unit(50) for generating and maintaining a constant reference voltage; a voltage dividing circuit(80) for sensing an output voltage and dividing the output voltage; a differential amplifying unit(60) for comparing the reference voltage and the divided voltage and amplifying the difference between the reference voltage and the divided voltage; and a power amplifying unit(70) for controlling the gain of the output voltage in accordance with the amplified difference.
