SC2597
Low Voltage DDR
Termination Regulator
Description
The SC2597 is designed to meet the latest JEDEC specifi-
cation for low power DDR3 and DDR4, while also support-
ing DDR and DDR2. The SC2597 regulates up to + 3A for
VTT and up to + 40mA for VREF.
The SC2597 also provides an accuracy of +1% over tem-
perature (which takes into account the internal resistor
divider) for VREF and VTT for the memory controller and
DRAM.
SC2597 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 power-
up or power-down.
The low external parts count combined with industry
leading specifications make SC2597 an attractive solution
for DDR through DDR4 termination.
