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 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 combination of

o ve r l o a d t h a t wo u l d c r e a t e e xc e s s i ve j u n c t i o n

temperature.

The APL1581 is available in both the through-hole and

surface mount versions of the industry standard 5-Pin

TO-263 and TO-252, SOP-8P, TO-252-4 power packages.

Ordering and Marking Information

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-020D 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).
