The present disclosure relates to the field of electronics and discloses a linear regulator. In the present disclosure, the linear regulator includes: a current bias module, a voltage bias module having positive temperature characteristics, and a flip voltage follower, where 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; and 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. The linear regulator in the present disclosure compensates negative temperature characteristics of the flip voltage follower by using the voltage bias module having the positive temperature characteristics. With no need for a reference voltage module, the output voltage also has good temperature characteristics, relatively low static power consumption, and a relatively small area on a chip.
