3A DDR BUS TERMINATION

REGULATOR

DESCRIPTION

The UR6515A is a linear regulator providing

up to 3A

transient peak current sourcing and sinking capability for DDR

SDRAM bus terminator applications while regulating an output

voltage to within 40mV. It contains a high speed operational amplifier

which provides fast load transient response and only requires 10uF

of ceramic output capacitance.

The UR6515A output termination voltage tracks the reference

Additional features include current limiting protection and thermal

shutdown protection.

FEATURES

*DDR1/ DDR2 termination voltage applications

*Low output voltage offset within 20mV

*Source and sink 3A peak current

*Adjustable output voltage by external resistors

*Integrated power MOS devices

*Suspend to RAM(STR) functionality

*Current Limiting Protection

*Thermal Shutdown Protection

*Cost-effective and easy to use
