Overview
The TPS51200AQDRCTQ1 is a sink and source double-data-rate (DDR) termination regulator designed by Texas Instruments. This device is specifically tailored for low input voltage, low-cost, and low-noise systems where space efficiency is crucial. It supports DDR, DDR2, DDR3, DDR3L, Low-Power DDR3, and DDR4 VTT bus termination applications. The regulator maintains a fast transient response and requires a minimum output capacitance of only 20 μF. It is available in a thermally efficient 10-pin VSON package and is rated both Green and Pb-free, operating over a temperature range of –40°C to 125°C.
