LVD SCSI 27-Line Regulator
General Description
The DS2129 is a triple-output voltage regulator for
27-line, low-voltage-differential (LVD) SCSI termination
for SPI-2 and SPI-3 applications using LVD termination
networks. The device provides reference voltages and
bias currents for LVD-termination resistor pi ( π ) net-
works. With a pi network (475 Ω , 121 Ω , 475 Ω ), the
DS2129 meets the common-mode bias, differential
bias, and termination-impedance requirements of SPI-2
(Ultra2) and SPI-3 (Ultra3). The device also provides a
1.3V output for DIFFSENSE signaling, and includes pro-
tection features such as thermal shutdown and active
current limiting.
