The APL1581 series of high performance positive voltage regulators are designed for use in applications requiring very low dropout voltage at 5Amp.
TheAPL1581can provide aoutput 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 reduced 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.
TheAPL1581 is available in both the through-hole and surfacemount versions of the industry standard 5-Pin TO-220 and TO-263, TO-252, SOP-8-P power packages.
