Overview
The TPS51200AQDRCRQ1, produced by Texas Instruments, is a sink and source double-data-rate (DDR) termination regulator. This device is specifically designed for low input voltage, low-cost, and low-noise systems where space is a critical factor. It is optimized for DDR, DDR2, DDR3, Low Power DDR3, and DDR4 VTT bus termination applications. The regulator maintains a fast transient response and requires a minimum output capacitance of 20 μF. It also supports remote sensing and provides an open-drain PGOOD signal for monitoring output regulation and an EN signal for discharging VTT during S3 (suspend to RAM) states.
