Abstract
A 1.7V 100mA capacitor-less CMOS low-dropout (LDO) regulator for system-on-chip applications which can both reduce board space and external pins is presented. By using a combination of fast transient improvement and frequency compensation method, the proposed LDO regulator provides a fast transient response, as well as good stability during the whole variation of load current. The proposed LDO regulator has been implemented in a 0.18mm CMOS process, and the active chip area is 0.15mm^2. The voltage derivation is less than 30mV for the load current change between 0 and 100mA. The dropout voltage is about 300mV at 100mA load current.
