Linear Regulators Theory of Operation and Compensation Introduction

这篇文章讲述了Linear Regulators的原理,NPN regulators,low-dropout(LDO)regulators和quasi-LDO的区别。还有大家非常关心的闭环的稳定性,ESR和稳定性的关系/输出电容的选择,P-FET LDO的优点。我想不算太了解LDO的人看了这篇文章,会有很大的收获。Linear Regulators:Theory of Operation and Compensation National SemiconductorLinear Regulators:TheoryApplication Note1148Chester Simpsonof Operation and May2000CompensationIntroductionThe explosive proliferation of battery powered equipment inthe past decade has created unique requirements for avoltage regulator that cannot be met by the industry stan-dards like the LM340or the LM317.These regulatorsuse anNPN Dar
