technical field [0001] The invention relates to the field of semiconductor integrated circuits, in particular to a high-voltage stabilizing circuit with current compensation. Background technique [0002] At present, there are usually two solutions for high-voltage regulator circuits used in the field of semiconductor integrated circuits. One is a voltage regulator circuit made of high-voltage PMOS and high-voltage NMOS. The use of high-voltage devices will significantly increase the production cost. [0003] The other is to use a general-purpose voltage clamping circuit. The disadvantage is that the driving capability is limited, and the power consumption will increase rapidly when the driving capability increases. Therefore, a high voltage stabilizing circuit with simple structure, large driving capability and low power consumption is needed.
