DDR TERMINATION

REGULATOR

DESCRIPTION

The UTC UR5596 is a linear bus termination regulator and

designed to meet JEDEC SSTL-2(Stub-Series Terminated

Logic) specifications for termination of DDR-SDRAM. It also can

be used in SSTL-3 or HSTL(High-Speed Transceiver Logic)

scheme. The device contains a high-speed OP AMP to provide

excellent response to the load transients, and can deliver 1.5A

continuous current and transient peaks up to 3A in the

application as required for DDR-SDRAM termination.

SOP-8

The UTC UR5596 also incorporates a V_SENSEpin to provide

superior load regulation and a V_REFoutput as a reference for the

chipset and DIMMs. Besides, an active low shutdown (SHDN)

pin provides Suspend To RAM (STR) functionality. When SHDN

is pulled low the V_TToutput will tri-state providing a high

impedance output, but, V_REFwill remain active. A power savings

advantage can be obtained in this mode through lower

quiescent current.

*Pb-free plating product number: UR5596L

Regarding the output, V_TTis capable of sinking and sourcing

current while regulating the output voltage equal to V_DDQ/2. The

output stage has been designed to maintain excellent load

regulation while preventing shoot through. The UTC UR5596

also incorporates two distinct power rails that separates the

analog circuitry from the power output stage. This allows a split

rail approach to be utilized to decrease internal power

dissipation and permits UTC UR5596 to provide a termination

solution for DDRII SDRAM.
