The SPI-8000TW series (SPI-8001TW, SPI-8002TW and SPI-8003TW) are a regulator IC provided with various functions required for the buck regulator as well as protection functions against overcurrent and overheat. Two of 1.5A variable outputs are provided in a package for surface mounting to realize a small and highly efficient switching regulator.


・On-board local power supply
・OA equipment
・For stabilization of the secondary-side output voltage of switching power supply
