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. A power savings advantage can be
obtained in this mode through lower quiescent
current.
The EUP7998 is available in the 3mm × 3mm
TDFN-10 and SOP-8 (EP) packages.
