This paper proposes an output-capacitorless low-dropout (LDO) regulator with ultra-low quiescent power. It applies an adaptive error amplifier to improve the bandwidth and transient response during heavy load, and a second gain stage to improve the stability during light load. Furthermore, an overshoot and undershoot reduction circuit is used to shorten the settling time when output load is changed. The LDO is fabricated in 0.18 mu m CMOS process and occupies a chip area of 0.06mm(2). The LDO is measured to output a stable voltage at 1.6V with a quiescent power of 1.8 mu W. The experimental results also show a good transient response. |
