本文提出了一种可扩展且PCB友好的菊花链方法，用于并行化LDO稳压器，解决了直接并联LDO时因器件差异导致电流不均衡和热失控的问题，实现了2.613%的电流共享精度。
applications presents a challenge for chip-level thermal management and also tends to be inefficient. Straightforward parallelizing of LDOs to increase output current is a flawed approach since subtle variations between devices even with the state-of-the-art manufacturing techniques can cause one of the LDOs to take over the maximum current, and thus enter current limit or thermal shutdown leading to instability and loss of regulation. Parallelizing regulators [1-6] to share the high output current equally across each regulator while preserving regulation and stability and to spread the dissipated heat uniformly is thus a challenging design problem. Stable parallel operation can be accomplished by placing all the regulators on a
