DDR TERMINATION

REGULATOR

DESCRIPTION

The UTC UR5595 is a linear bus termination regulator designed

to meet JEDEC SSTL-2 and SSTL-3 (Stub Series Terminated

Logic) specifications for termination of DDR-SDRAM. The device

contains a high-speed operational amplifier 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.

With an independent V_SENSEpin, the UR5595 can provide

superior load regulation. The UR5595 provides a V_REFoutput as

the reference for the application of the chipset and DIMMs.

The output, V_TT, is 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 and with fast

response time to minimum the transition preventing shoot-through.

The UTC UR5595 also incorporates two distinct power rails that

separates the analog circuitry (AVIN) from the power output stage

(PVIN). This power rail split can be utilized to reduce the internal

power dissipation. And this also permits UTC UR5595 to provide a

termination solution for DDRII SDRAM.
