3A DDR BUS TERMINATION

REGULATOR

DESCRIPTION

The UR6515D is a linear regulator sourcing or sinking

continuous 2A or up to 3A transient peak current while regulating an

output voltage to within 40mV in the DDR SDRAM bus terminator

applications. It contains a high speed operational amplifier which

provides fast load transient response and only requires 10uF of

ceramic output capacitance.

The UR6515D output termination voltage tracks the reference

Additional features include current limiting protection and thermal

shutdown protection.
