General Description
The APL1581 series of high performance positive voltage regulators are designed for use in applications requiring 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 reduced
heat dissipation compared to regular LDOs. The APL1581 also provides excellent regulation over line , load , and temperature variations.
