SLUS413B -- MAY 1999 -- REVISED NOVEMBER 2002  
LOW-VOLTAGE DIFFERENTIAL SCSI (LVD)  
27-LINE REGULATOR SET  
FEATURES  
DESCRIPTION  
The UCC561 low-voltage differential (LVD) regulator  
D
SCSI SPI--2, SPI--3 and SPI--4 LVD SCSI  
27-Line, Low-Voltage Differential Regulator  
set is designed to provide the correct references  
voltages and bias currents for LVD termination resistor  
networks (475 9, 121 9, and 475 9). The device also  
provides a 1.3-V output for “diff sense” signaling. With  
the proper resistor network, theUCC561 solutionmeets  
the common mode bias impedance, differential bias,  
and termination impedance requirements of SPI--2  
(Ultra2), SPI--3 (Ultra3/Ultra160) and SPI--4 (Ultra320).  
The UCC561 is not intended for SPI--5 applications.

This device incorporates into a single monolith, two  
sink/source reference voltage regulators, a 1.3-V  
buffered output and protection features. The protection  
features include thermal shutdown and active  
current-limiting circuitry. The UCC561 is offered in  
16-pin SOIC (DP) package.
