Description

The APL5508 / APL5508R / APL5509 / APL5509R  is low-power  and low dropout  li near  regulator,  which  operates  in  the  rage  of 2.7V to 6V input voltage and delivers up to 560mA output current. T ypical dropout voltage is only 600mV (typical) at 560mA output current. The  APL5508/5508R/5509/5509R regulator with low 60mA quiescent current is ideal for battery  powered  system  appliances. The APL5508/5508R/5509/5509R  regul ator  i s  stabl e  wi th  a  4. 7mF  cerami ccapacitor. The  features of  current-limit, short  circuit current  l imi t,  and  over-temperature  protecti on  protect  the device against current over loads and over temperature.The APL5508/5508R/5509/5509R  regulator is available
in SOT-23-3, SOT-89, or SOT-223 packages.
