Low Voltage Integrated DDR
Termination Regulator
POWER MANAGEMENT
Description
The SC2596 is an integrated linear DDR termination
device, which provides a complete solution for DDR
termination regulator designs; while meeting the JEDEC
requirements of SSTL-2 and SSTL-18 specifications for
DDR-SDRAM termination.
The SC2596 regulates up to +/- 2.5A for DDR-I and +/-
1.5A for DDR-II application requirements.
V
TT
is regulated to track the V
REF
voltage over the entire
current range with shoot through protection.
A V
SENSE
pin is incorporated to provide excellent load
regulation, along with a buffered reference voltage for
internal use.
The SC2596 also features a disable function which is to
tri-state the output during Suspend To Ram (STR) states
by pulling the EN pin low.
