Abstract

The low dropout regulator (LDO) is an essential building block for modern integrated circuits. Traditional analog design faces formidable challenges as technology scales down, such as lower supply voltage and channel length modulation. Digital LDOs do not have the problems that analog LDOs have, but they usually have worse performance metrics. Therefore, a time-based LDO is proposed to combine the merits of both analog and digital together. In the end, the LDO achieves 0.6-1 V supply voltage range and 0.5-0.9 V output voltage range. The maximum output current is 50 mA and the worst case transient time is 1.58 μs under 0.6 V supply voltage. The maximum current efficiency is 99.98%.
