APL5509 Overview
The APL5508/5508R/5509/5509R is low-power and low dropout linear regulator, which operates in the rage of 2.7V to 6V input voltage and delivers up to 560mA output current. Typical dropout voltage is only 600mV (typical) at 560mA output current. The APL5508/5508R/5509/5509R regulator with low 60µA quiescent current is ideal for battery powered system appliances.
