3A Sink/Source DDR Termination Regulator w/ VTTREF Buffered Reference for DDR2, DDR3, DDR3L and DDR4

Favorite

Overview

The NCP51200 is a source/sink Double Data Rate (DDR) termination regulator specifically designed for low input voltage and low-noise systems where space is a key consideration. The NCP51200 maintains a fast transient response and only requires a minimum output capacitance of 20 uF. The NCP51200 supports a remote sensing function and all power requirements for DDR VTT bus termination. The NCP51200 can also be used in low-power chipsets and graphics processor cores that require dynamically adjustable output voltages. In addition, the NCP51200 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 NCP51200 is available in the thermally-efficient DFN10 Exposed Pad package, and is rated both Green and Pb-free.
