General Description

The APL1582 of high performance positive voltage regulators are designed for use in applications requiring very low dropout voltage at 3Amps .

The APL1582 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 reduced heat dissipation compared to regular LDOs. The APL1582 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 APL1582 is available in both the through-hole and surface mount versions of the industry standard 5-Pin TO-220, TO-252 and TO-263 power packages .
