UR6512

DESCRIPTION

The UR6512 is a linear regulator providing up to 2A for DDR

1/DDR 2 and 1.5A for DDR 3 transient peak current and has

sourcing and sinking capability for DDR SDRAM 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 UR6512 output termination voltage tracks the reference

voltage applied at V REF pin. A resistor divider connected to V IN , GND

and V REF pins is used to force the reference voltage to V REF pin.

Additional features include current limiting protection and thermal

shutdown protection.
