Semtech SC2598

The SC2598 is designed to meet the latest JEDEC specification for low power DDR3 and DDR4, while also supporting DDR and DDR2. The SC2598 regulates up to + 3A for VTT and up to + 40mA for VREF.
The SC2598 also provides an accuracy of +1% over temperature(which takes into account the internal resistor divider) for VREF and VTT for the memory controller and DRAM.
SC2598 protection features include thermal shutdown with auto-restart for VTT and over-current limit for both VTT and VREF.
Under-Voltage-Lock-Out circuits are included to ensure that the output is off when the bias voltage falls below its threshold, and that the part behaves elegantly in powerup or power-down.
The low external parts count combined with industry leading specifi cations make SC2598 an attractive solution for DDR through DDR4 termination.
