摘要: Disclosed is a low dropout linear regulator comprising a power transistor and an error amplifier comprising a first input stage, a second input stage and a control circuit. The first input stage comprises a first pair of transistors receiving an output voltage and a reference voltage, the second input stage comprises a second pair of transistors receiving the output voltage and the reference voltage, the first and second pairs of transistors have different conductivity types. The control circuit controls turn-on and turn-off states of the first input stage according to the reference voltage, and turns on the first input stage when the reference voltage is less than a preset threshold, so that the error amplifier operates normally and the output voltage changes smoothly. When the reference voltage is greater than the preset threshold, the control circuit turns off the first input stage so that only the second input stage operates.
