Distributed LDOs can effectively mitigate the global IR drop and improve the local transient performances for a high-current large-area power delivery network. However, compared to traditional standalone LDO designs, they face integration, current sharing, and stability challenges. In this chapter, we discuss and analyze these issues in detail and introduce two distributed LDO integration solutions: on-side integration and embedded integration. In addition, we focus on three distributed LDO control solutions: parallel distributed LDO, neighbor cooperative distributed LDO, and dual-loop distributed LDO. For each type, we provide an overview of the architecture and core circuit design.
