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.
