A Fast-Transient-Response Fully-Integrated Digital LDO With Adaptive Current Step Size Control

A 0.6-V 100-mA fully-integrated digital low-dropout regulator (DLDO) with adaptive current step size control is presented in this paper. By dividing the main power PMOSs into ten blocks with different unit-cell sizes, the proposed DLDO can turn-on/-off small power PMOSs in light load and large ones...
