L1581 Overview
The L1581 is a positive and very low dropout voltage regulator with 5A output current capability. When supplying 2.5V or 2.8V on Motherboards or VGA Card where both 5V and 3.3V supplies are available, the superior dropout characteristics of the L1581 result in reduced heat dissipation pared to regular LDOs, thus allowing heat sink reduction. The adjustable version requires only two external resistors to set the...
