Abstract
A linear regulator includes: a current bias module, a voltage bias module having positive temperature characteristics, and a flip voltage follower. An input end of the current bias module receives an input voltage of the linear regulator, and an output end of the current bias module outputs a bias current. A first input end and a second input end of the voltage bias module receive the input voltage and the bias current, respectively, and an output end of the voltage bias module outputs a bias voltage. A first input end and a second input end of the flip voltage follower receive the input voltage and the bias voltage, respectively, and an output end of the flip voltage follower outputs an output voltage of the linear regulator.
