Abstract:Low dropout (LDO) regulators are crucial components in power management systems for portable, i.e., battery-powered, devices. However, the design of LDO regulators presents a challenging trade-off between dynamic performance, power consumption, and area efficiency. This paper proposes a novel LDO regulator design that addresses these challenges by employing the reverse nested Miller compensation (RNMC) with current buffers embedded within the own class AB high gain error amplifier (EA) topology, and a time res… Show more
