This paper presents a novel capacitor-less low-dropout regulator (LDO) for mobile applications. The proposed capacitor-less LDO utilizes multiple feedback loops to satisfy several design challenges for some mobile applications which were not considered in the previous capacitor-less LDOs. The proposed LDO has a wide bandwidth of 3.03 MHz at a load current of 150 mA with a bias current of 40 $\mu\mbox{A}$ , and the best line and load regulations of 0.0024%/V and 0.0000417%/mA, respectively, which are improvements over previously reported LDOs. This chip has a 100 mV dropout voltage with a 150 mA maximum load current. A total capacitance of 29 pF was used with a chip size of 0.279 $\mbox{mm}^{2}$ .read more
