The TL2217-285 is a low-dropout (1 V) fixedvoltage regulator specifically designed for small computer systems interface (SCSI) alternative 2 active signal termination. The TL2217-285 1-V maximum dropout ensures compatibility with existing SCSI systems, while providing a wide TERMPWR voltage range. At the same time, the 1.5% initial tolerance on its 2.85-V output voltage ensures a tighter line-driver current tolerance, thereby increasing system noise margin. The fixed 2.85-V output voltage of TL2217-285 supports the SCSI alternative 2 termination standard, while reducing system power consumption. The 1-V maximum dropout voltage brings increased TERMPWR isolation, making the device ideal for battery-powered systems. The TL2217-285, with internal current limiting, overvoltage protection, ESD protection, and thermal protection, offers designers enhanced system protection and reliability.
