    Low DropOut Converter (LDO) is commonly employed as voltage down converter (VDC) because of its high compatibility with System on Chips (SoCs), but in general, LDO is not so high power efficient. This paper presents an Autonomous Controlled Cascaded LDOs power system which achieves about doubled power efficiency of the conventional LDO systems. In proposed architecture, existing logic circuitries are divided into two load group, and electrical charges are shared among the blocks and a tank circuit. We confirmed that our architecture makes effective use of 88.9% of the battery energy by simulation which is comparable to that of switching regulators whereas ours is easier to implement in SoCs.
