General Description
The APL1581 series of high performance positive voltage regulators are designed for use in applications requiring 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 temperature variations.
Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal
limiting provides protection against any combination 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-263 and TO-252, SOP-8P, TO-252-4 power packages.
