General Description
The RT9005A/B is
a dual-output linear regulator for DDR-
SDRAM VDDQ supply and termination voltage VTT supply.
The Regulator is capable of actively sinking or sourcing
up to 2A. The output termination voltage can be tightly
regulated to track 1/2 VDDQ by two external voltage divider
resistors.
