NIKO-SEM Dual Input Ultra Low Dropout Voltage Regulator (ULDO) FEATURES L1581 Series TO-252 GENERAL DESCRIPTION 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 compared to regular LDOs, thus allowing heat sink reduction. The adjustable version requires only two external resistors to set the output. The L1581 features a low dropout of less than 600mV and offers fast transient response, remote sense, internal limiting, thermal shutdown and safe operating area protection of the output device.
