Most LDO regulators before are off-chip so that they are hard to meet the demands of SOC solutions. This thesis is target on SOC applications and analyzes the challenges of stability, transient regulation and line regulation, etc. Trade-off relations between different characterizations are seriously discussed. In order to meet the demand of high precision and self-stability, a newly LDO structure is proposed and design process is carefully described, which manifest many design points. A PMOS is chosen to be the output transistor of this on-chip LDO. To maintain stability, miller capacitor in serious with nulling resistor is used.
