APL1581

APL1581 DUAL INPUT LOW DROPOUT REGULATOR Features General Description Adjustable or Fixed Output 520mV typ. Dropout at 5A in Dual Power Voltage Mode Remote Sense Pin Available 2% Accuracy Over Temperature Range Built-In Over-Temperature Protection Built-In Current Limit 5 Pin TO-263 and TO-252, SOP-8P, TO-252-4 Packages Lead Free and Green Devices Available (RoHS Compliant) Applications Microprocessor Supplies Chip Set Supplies VGA Card Power LCD Monitor Power 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.
