... The APL1581 series of high performance positive volt- age regulators are designed for use in applications re- quiring 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 ...

... Output Current (A) Application Information General The APL1581 (adjustable or fixed) regulator ter- minal device designed specifically to provide extremely low dropout voltages comparable to the PNP type with- out the disadvantage of the extra power dissipation due to the base current associated with PNP regulators. ...

... RP is made up of the PC traces and /or connector resistance between the regulator and the processor now connectedinside the regulation loop of the APL1581 and for reasonable val- ues of RP the load regulation at the load will be negligible. Voltage drops due to RP are not eliminated; ...
