General Description
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 bat-
tery powered system appliances. The APL5508/5508R/
5509/5509R regulator is stable with a 4.7µF ceramic
capacitor. The features of current-limit, short circuit cur-
rent limit, and over-temperature protection 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.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
