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 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 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-220 and TO-263, TO-252, SOP-8P power packages.
