2A DDR BUS TERMINATION

REGULATOR

DESCRIPTION

The UR5512 is a linear regulator which provides up to 2 Amp

bi-directional driving and sinking capability for DDR SDRAM bus

terminator application. The output termination voltage tracks the

pin.

The UR5512 contains a high-speed operational amplifier to

provide excellent response to line/load transient. An active-low

Additional features include current limiting protection, on-chip

thermal shut-down protection.
