描述 Description

Key Features:Compliant with SPI-2 (Ultra2), SPI-3 (Ultra160), and SPI-4 (Ultra320) 2.7V to 5.25V Operation200mA Source/Sink CapabilityDIFSENS Line DriverCurrent Limit and Thermal ProtectionPin Compatible With Unitrode UCC561Description:The LX5261 is a source/sink regulator designed to provide the correct reference voltages and bias currents for SCSI LVD applications. With the proper LVD termination network (475?, 121?, 475?), the LX5261 assures that LVD performance is compliant to the SPI-2 (Ultra2), SPI-3 (Ultra160) and SPI-4 (Ultra320) specification.The LX5261 provides two fixed regulated outputs (1.75V and 0.75V)each capable of sourcing / sinking 200mA, along with a buffered 1.3V output for DIFSENS signaling.The LX5261 features on-chip trimming of the internal voltage enabling precise output voltages; typically ±1% of its specified value. Thermal Shutdown and Current Limiting is integrated on-chip. The LX5261 is available in the 16-pin SOIC (DP) package.
