L1581中文资料Dual Input Ultra Low Dropout Voltage Regulator (ULDO) TO-252数据手册NIKO-SEM规格书

描述 Description

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.
The L1581 is a five terminal adjustable voltage regulator available in the popular 5 pin TO-252 packages.FEATURES
