Reference voltage regulator circuit structure with high power supply rejection ratio

The utility model relates to a reference voltage regulator circuit structure with a high power supply rejection ratio. The reference voltage regulator circuit structure with the high power supply rejection ratio comprises a power supplying audion and a pre-reference voltage source circuit module, a secondary reference voltage source circuit module which are in sequential cascade connection. An input end of the pre-reference voltage source circuit module is connected with a power supply through the power supplying audion. An output end of the pre-reference voltage source circuit module is connected with an input end of the secondary reference voltage source circuit. An output end of the secondary reference voltage source circuit module is an output end of the reference voltage regulator circuit structure. When the reference voltage regulator circuit structure with the high power supply rejection ratio is used, the working voltage of a secondary reference voltage source is rarely influenced by power supply volt
