Texas Instruments, 0.75 → 1.25 V Voltage Regulator, 5.5A, 1-Channel, Adjustable, ±5% 10-Pin, SON TPS51200DRCR

Designed specifically for bus termination in DDR and QDR memory applications. These sink/source tracking termination regulators are aimed for space saving, low-cost applications with low external part counts.

The Texas Instruments TPS51200 device is a sink and source double data rate (DDR)termination regulator specifically designed for low input voltage, low-cost, low-noise systems where space is a key consideration. It maintains a fast transient response and requires a minimum output capacitance of only 20 μF. It supports a remote sensing function and all power requirements for DDR, DDR2, DDR3, DDR3L,Low-Power DDR3 and DDR4 VTT bus termination.
