TPS51200DRCT Description


The TPS51200 is a sink and source double data rate (DDR) termination regulator that is specifically developed for low input voltage, low-cost, low-noise systems with limited space.
The TPS51200 has a quick transient response and requires only 20 F of output capacitance. The TPS51200 fulfills all power needs for DDR, DDR2, DDR3, DDR3L, Low-Power DDR3 and DDR4 VTT bus termination as well as remote sensing.
Furthermore, the TPS51200 includes an open-drain PGOOD signal for monitoring output regulation and an EN signal for discharging VTT during S3 (suspend to RAM) for DDR applications. The TPS51200 comes in the thermally efficient 10-pin VSON thermal pad packaging and is both Green and Pb-free. It has a temperature range of –40°C to +85°C.
