Abstract :
A CMOS low dropout regulator (LDO) with a new pole-zero pairs cancellation compensation scheme is presented. LDO using this proposed compensation technique provides stable output voltage with any load capacitor. The only constraint on the equivalent series resistance (ESR) of the load capacitor is that it should be less than the load resistance. It is especially suitable for system-on-chip integration applications and board size reduction.
