SC2596 Datasheet | SEMTECH

Low Voltage Integrated DDR Termination Regulator POWER MANAGEMENT Description The SC2596 is an integrated linear DDR termination device, which provides a plete 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. .. Features ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ Sourcing or sinking 2.5A for DDR-I Sourcing or sinking 1.5A for DDR-II AVCC undervoltage lockout Reference output Minimum number of external ponents Accurate internal voltage divider Disable function, puts device into sleep mode Thermal shutdown Over current protection Available in SOIC-8 EDP package WEEE and Ro HS pliant VTT is regulated to track the VREF 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.
