TPS51200DRCR DDR termination regulator
The TPS51200DRCR is a high-performance sink/source DDR termination regulator from Texas Instruments, specifically designed to provide the precise VTT termination voltage and reference voltage (VTTREF) required by DDR2, DDR3, DDR4, and low-power DDR memory systems. This device integrates a high-current operational amplifier and a precision reference buffer in a single package, delivering a compact and efficient solution for memory bus termination. It operates from an input voltage (VDDQ) of 1.0V to 3.6V and can source/sink up to 3A of current to maintain signal integrity on the memory bus. Its primary function is to generate a stable VTT voltage exactly half of VDDQ and a tracking reference voltage, which are critical for reducing signal reflections and ensuring reliable data communication between the memory controller and DRAM modules.
This regulator features a high-speed amplifier with a slew rate of 30 V/µs, enabling it to respond rapidly to current transients on the memory bus. It provides a highly accurate VTT output voltage of VDDQ/2 ± 10 mV and a VTTREF output of VDDQ/2 ± 5 mV. Key specifications include a low dropout voltage and a standby current of less than 60 µA when disabled.
