一种具有自适应极点跟踪频率补偿技术的高效率快速瞬态响应低压差线性稳压器

An advanced smooth pole tracking technique for a low dropout (LDO) regulator with a ceramic capacitor is presented in this article. Normally, the dominant pole is at the output of an LDO and becomes load dependent, which may cause a loop stability issue during the whole load-current application range. The proposed frequency compensation methodology with adaptive load resistor control of an error a...
