Digitally Controlled Low-Dropout Regulator with Fast-Transient and Autotuning Algorithms

  title={Digitally Controlled Low-Dropout Regulator with Fast-Transient and Autotuning Algorithms},
  author={Yen-Chia Chu and Le-Ren Chang-Chien},
  journal={IEEE Transactions on Power Electronics},
A digitally controlled low-dropout voltage regulator (LDO) that can perform fast-transient and autotuned voltage is introduced in this paper. Because there are still several arguments regarding the digital implementation on the LDOs, pros and cons of the digital control are first discussed in this paper to illustrate its opportunity in the LDO applications. Following that, the architecture and configuration of the digital scheme are demonstrated. The working principles and design flows of the… CONTINUE READING
