Abstract

Embodiments of the present disclosure describe methods, apparatuses, and systems for hybrid low dropout regulator (LDO) architecture and realization to provide high power supply rejection ratio (PSRR) and high conversion efficiency (CE), and other benefits. The hybrid LDO may be coupled with dual rails for its analog LDO branch and digital LDO respectively to achieve high PSRR and high CE by utilizing the hybrid architecture with several feedback loops. Other embodiments may be described and claimed.
