description
The TL-SCSI285 is a low-dropout (0.7-V)
fixed-voltage regulator specifically designed for
small computer systems interface (SCSI)
alternative 2 active signal termination. The
TL-SCSI285 0.7-V maximum dropout ensures
compatibility with existing SCSI systems while
providing a wide TERMPWR voltage range. At the
same time the
±
1% initial tolerance on its 2.85-V
output voltage ensures a tighter line driver current
tolerance, thereby increasing the system noise
margin.
The fixed 2.85-V output voltage of the
TL-SCSI285 supports the SCSI alternative 2
termination standard while reducing system
power consumption. The 0.7-V maximum dropout
voltage brings increased TERMPWR isolation,
making the device ideal for battery-powered
systems. The TL-SCSI285, with internal current
limiting, overvoltage protection, ESD protection,
and thermal protection offers designers enhanced
system protection and reliability.
When configured as a SCSI active terminator, the
TL-SCSI285 low-dropout regulator eliminates the
220-
and the 330-
resistors
required for each
transmission line with a passive termination
scheme, reducing significantly the continuous
system power drain. When placed in series with
110-
resistors, the device matches the imped-
ance level of the transmission cable and
eliminates reflections.
