This paper presents an output cap-less low-dropout regulator (LDO) using a voltage damper and body bias feedback for fast load transient response. The voltage damper makes load transient fast. To make the LDO react to relatively slow distortion of the output, the body bias feedback is included. The proposed LDO regulator is fabricated in a 0.18μm CMOS process with an active area of 0.026mm2 and an on-chip capacitance of 9.32pF. The operating conditions are set to an input voltage of 1.8V, a maximum load current of 100mA, and an output voltage of 1.6V. The maximum undershoot was 284 mV and the maximum overshoot was 199 mV.
