Texas Instruments TPS51200 Sink/Source DDR Termination Regulator
Texas Instruments TPS51200 Sink/Source DDR Termination Regulator is specifically designed for low-input voltage, low-cost, low-noise systems where space is a crucial consideration. The TPS51200 maintains a fast transient response and only requires a minimum output capacitance of 20µF. The TPS51200 supports a remote sensing function. This device also supports all power requirements for DDR, DDR2, DDR3, Low-Power DDR3, and DDR4 VTT bus termination. The Texas Instruments TPS51200 provides an open-drain PGOOD signal to monitor the output regulation and an EN signal that can be used to discharge VTT during S3 (suspend to RAM) for DDR applications.
