Product Summary
The TPS51206DSQR is a sink/source double date rate (DDR) termination regulator with VTTREF buffered reference output. It is specifically designed for low input voltage, low cost, low external component countsystems where space is a key consideration. The TPS51206DSQR maintains fast transient response and only requires 1× 10-μF of ceramic output capacitance. The TPS51206 supports a remote sensing function and all power requirements for DDR2, DDR3 and Low-Power DDR3 (DDR3L) VTT bus. The applications of the TPS51206DSQR include DDR2/DDR3/DDR3L Memory Power Supplies, SSTL_18, SSTL_15, SSTL_135 and HSTL Termination.
