This letter proposes an n-type output capacitorless low-dropout regulator (LDO) with high power supply rejection (PSR) and fast transient response. To enhance both the performances, a multiple-feedback loop structure is proposed. The LDO obtained a PSR of -40 dB (-25 dB) at 1 MHz with load currents of 100 mA (600 mA). The LDO achieved an undershoot of 116 mV when the load changes from 1 to 600 mA, while consuming a quiescent current of 27.5 mu A. The chip was fabricated in the 180-nm CMOS process with an area of 0.063 mm(2).
