Features

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 .
