The APL1581 series of high performance positive volt-
age regulators are designed for use in applications re-
quiring very low dropout voltage at 5Amp.
The APL1581 can provide a output voltage at the range of
1.25V to 2.55V where both 5V and 3.3V voltage supplies
are available.
The superior dropout characteristics result in reducing
heat dissipation compared to regular LDOs. The APL1581
also provides excellent regulation over line, load, and tem-
perature variations.
Current limit is trimmed to ensure specified output cur-
rent and controlled short-circuit current. On-chip thermal
limiting provides protection against any combina-
tion of overload that would create excessive junction
temperature.
The APL1581 is available in both the through-hole and
surface mount versions of the industry standard 5-Pin
TO-220 and TO-263, TO-252, SOP-8P power 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.
