EUP7998 Sink/Source DDR Termination Regulator DESCRIPTION The EUP7998 is a high performance linear regulator designed to provide power for termination of a DDR memory bus. It significantly reduces parts count, board space and overall system cost over previous switching solutions. The EUP7998 maintains a fast transient response using only 20μF or 30μF output capacitance. The EUP7998 supports a remote sensing function and all power requirements for DDR, DDR2, DDR3 and Low Power DDR3/DDR4 VTT bus termination. The EUP7998 provides current and thermal limits to prevent damage to the linear regulator. Additionally, The EUP7998 generates an open-drain PGOOD signal to monitor the output regulation. An active high enable pin EN can pull VTT low, but REFOUT will remain active.
