General Description
The ET51200 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. The ET51200 maintains a fast transient response and requires a minimum output capacitance of only 20μF. The ET51200 supports a remote sensing function and all power requirements for DDR, DDR2, DDR3, DDR3L, Low-Power DDR3 and DDR4 VTT bus termination. In addition, the ET51200 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. The ET51200 is available in the thermally efficient DFN10 thermal pad package, and is rated both Green and Pb-free. It is specified from -40°C to +85°C.
