LINEAR INTEGRATED CIRCUIT
2A DDR BUS TERMINATION
REGULATOR
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 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 Termination Voltage Applications * 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
