com Rev 1; 2/06 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) networks.
With a pi network (475Ω , 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 protection features such as thermal shutdown and active current limiting.
