Abstract - This paper presents a novel two-stage low dropout
regulator (LDO) that minimizes output noise via a pre-regulator
stage and achieves high power supply rejection via a simple
subtractor circuit in the power driver stage. The LDO is
fabricated with a standard 0.35um CMOS process and occupies
0.26mm2 and 0.39mm2 for single and dual output respectively.
Measurement showed PSR is 60dB at 10kHz and integrated noise
is 21.2uVrms ranging from 1kHz to 100kHz.
