Description

technical field [0001] The invention relates to the field of circuit voltage stabilization, in particular to a high-voltage-resistant voltage-stabilizing integrated circuit. Background technique [0002] The voltage stabilizing circuit refers to a power supply circuit that can keep the output voltage basically unchanged when the input grid voltage fluctuates or the load changes. With the rapid development of society, the number of electrical equipment is increasing day by day. However, the aging and development lag of power transmission and distribution facilities, as well as poor design and insufficient power supply cause the voltage of end users to be too low, while the voltage of end users is often too high. For electrical equipment, especially high-tech and precision equipment with strict voltage requirements, it seems that there is no insurance. Unstable voltage will cause fatal injury or malfunction to the equipment, affect production, cause delay in delivery, unstabl...
