2A DDR BUS TERMINATION

REGULATOR

DESCRIPTION

The UTC 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 UTC 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.

FEATURES

* DDR-I and DDR-II termination voltage applications

* Driving and sinking current up to 2A

* Low output voltage offset (within 20mV@±2A)

* Adjustable output voltage by external resistors

* Suspend to RAM (STR) functionality

* Current limiting protection

* Thermal protection
