A Hybrid Low-Dropout Regulator with Load Regulation Correction

Abstract

A hybrid low-dropout regulator (LDO) based on proposed load-regulation correction (LRC) is presented in this paper. The proposed hybrid LDO operates at an ultra-low supply of 0.6 V. It provides fast load transient response by proposed three-level switching and achieve high output accuracy by proposed LRC. The hybrid LDO is implemented in a 65-nm CMOS technology. The normalized error of dc output voltage and figure-of-merit are 0.0067 V/V and 0.4755 ns, respectively.
