UR6515A

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

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.

FEATURES
