Title:
LINEAR REGULATOR
Document Type and Number:
WIPO Patent Application WO/2018/032308
Kind Code:
A1
Abstract:
A linear regulator, comprising: a current biasing module (6), a voltage biasing module (7) having positive temperature features, and a turnover voltage follower (8); an input terminal of the current biasing module (6) receives an input voltage of the linear regulator, and an output terminal of the current biasing module (6) outputs a bias current; a first input terminal and a second input terminal of the voltage biasing module (7) receive the input voltage and the bias current, respectively, and an output terminal of the voltage biasing module (7) outputs a bias voltage; a first input terminal and a second input terminal of the turnover voltage follower (8) respectively receive the input voltage and the bias voltage, and an output terminal of the turnover voltage follower (8) outputs an output voltage of the linear regulator. The linear regulator uses the voltage biasing module (7) having positive temperature features to compensate the negative temperature features of the turnover voltage follower (8), such that even without providing a reference voltage module, the output voltage still has good temperature features, relatively low static power consumption, and a relatively small area taken by a chip.
