LINEAR INTEGRATED CIRCUIT

1.8A DDR BUS TERMINATION

REGULATOR



DESCRIPTION

The UR6517 is a linear regulator providing up to 1.8A transient

current sourcing and sinking capability for DDR 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.

HSOP-8

The UR6517 output termination voltage tracks the reference

voltage applied at V_REFpin. A resistor divider connected to V_IN, GND

and V_REFpins is used to force the reference voltage to V_REFpin.

Additional features include current limiting protection and thermal

shutdown protection.



FEATURES

*DDR1/ DDR2/DDR3/DDR4 termination voltage applications

*Sink and Source Current

DDR2 1.8A Sink/Source @ V_IN=1.8V

DDR3 1.5A Sink/Source @ V_IN=1.5V

LPDDR3 1.2A Sink/Source @ V_IN=1.35V

DDR4 1.2A Sink/Source @ V_IN=1.2V

*Low output voltage offset within 20mV

*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
