摘要：

Design and Measurement results are presented for a fully integrated, linear, low-dropout regulator with a quiescent current of 12 mu A. The regulator is able to recover from full load steps with less than 10% change in the regulated voltage and in less than 2 mu s. The regulator reference is generated by a curvature-compensated bandgap reference. The reference uses only 9.8 mu A and has a temperature coefficient of 2.95-ppm/degrees C and can tolerate a wide range of input voltages from 3.2V to 8V with a line regulation of 160 mu V/V. These blocks are fabricated in 0.13 mu m CMOS process, do not require off-chip components and target power harvesting biomedical and lab-on-a-chip applications that require up to 5mA of current from a 3.3V supply.
