General Description
The APL5523 is a dual low dropout regulator with out-
put1 with 3.3V/0.5A and output2 with 1.8V/0.3A output
capability. In order to obtain lower dropout voltage and
faster transient response, which is critical for low volt-
age applications, the APL5223 has been optimized. The
dropout voltages are guaranteed at 0.6V at 0.5A for out-
put1 and 0.9V at 0.3A for output 2. Current limit is trimmed
to ensure specified output current and controlled short-
circuit current. On-chip thermal limiting provides protec-
tion against any combination of overload that would cre-
ate excessive junction temperatures. The APL5523 regu-
lator comes in a SOP-8 and SOP-8P 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).
ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and
advise customers to obtain the latest version of relevant information to verify before placing orders.
