2A DDR BUS TERMINATION

REGULATOR

DESCRIPTION

The UR6512 is a linear regulator providing up to 2A transient

peak current and has sourcing and sinking capability for DDR

SDRAM bus terminator applications while regulating an output

voltage to within 20mV. It contains a high speed operational amplifier

which provides fast load transient response and only requires 10uF

of ceramic output capacitance.

The UR6512 output termination voltage tracks the reference

Additional features include current limiting protection and thermal

shutdown protection.
