Abstract
An LDO circuit having a power supply rejection function, a chip, and a communication terminal. The LDO circuit includes a bandgap reference module provided with an intermediate frequency zero adjustment unit, an amplification module provided with an intermediate frequency zero generation unit, and a power output module. The bandgap reference module is connected to the amplification module, and the amplification module is connected to the power output module. For the purpose of power supply rejection at an intermediate frequency, the intermediate frequency zero adjustment unit in the bandgap reference module and the intermediate frequency zero generation unit in the LDO circuit are adjusted in coordination to better optimize the intermediate frequency power supply rejection performance.
