LOW-DROPOUT LINEAR REGULATOR AND CORRESPONDING METHOD

摘要

A low-dropout linear regulator includes an error amplifier comprising a cascaded arrangement of a differential amplifier and a gain stage having interposed therebetween a frequency compensation network for a loading current to flow therethrough. The regulator includes a current limiter inserted the flow-path of the loading current for the compensation network to increase the slew rate of the output of the differential amplifier by dispensing with the capacitive load in the frequency compensation network during load transients in the regulator.
