Abstract:
A ripple pre-amplification based fully integrated LDO pertains to the technical field of power management. The positive input terminal of a transconductance amplifier is connected to a reference voltage Vref, and the negative input terminal of the transconductance amplifier is connected to the feedback voltage V fb . The output terminal of the transconductance amplifier is connected to the negative input terminal of a transimpedance amplifier and the negative input terminal of an error amplifier. The positive input terminal of the transimpedance amplifier is connected to the ground GND, and the output terminal of the transimpedance amplifier is connected to the positive input terminal of the error amplifier. The gate terminal of the power transistor M P  is connected to the output terminal of the error amplifier, the source terminal of the power transistor M P  is connected to an input voltage V IN , and the drain terminal of the power transistor M P  is grounded.
