LINEAR INTEGRATED CIRCUIT
2A DDR BUS TERMINATION
REGULATOR
DESCRIPTION
The UR6511 is a linear regulator providing up to 2A 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.
The UR6511 output termination voltage tracks the reference
voltage applied at VREF pin. A resistor divider connected to VIN, GND
and VREF pins is used to force the reference voltage to VREF pin.
Additional features include current limiting protection and thermal
shutdown protection.
FEATURES
*DDR1/ DDR2/DDR3/Low Power DDR3 termination voltage
applications
*Sink and Source Current2A
*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
