Low dropout regulator with amplifier having feedback circuit

A low dropout regulator, comprising:

• an output circuit comprising a signal input end and a signal output end, wherein the signal input end is configured to receive an input voltage, and the signal output end is configured to output an output voltage;
• and
• an amplifier comprising:
• a first stage amplifier circuit comprising a positive input end, a negative input end, a positive output end and a negative output end;
• a second stage amplifier circuit comprising an input end and an output end, wherein the input end and the positive output end are coupled at a first node, and the output end is coupled to the output circuit;
• a first feedback circuit electrically connected between the negative output end and the output end, and configured to provide a positive feedback, wherein the first feedback circuit comprises a first capacitor and a third resistor, the first capacitor is coupled to the negative output end, and the third resistor is coupled between the first capacitor and the output end;
• and
• a second feedback circuit electrically connected between the first node and the output end.
