The TPS51200DRCT is a sink/source Double Data Rate (DDR) Termination Regulator, specifically designed for low input voltage, low-noise systems where space is a key consideration. The TPS51200DRCT maintains a fast transient response and only requires a minimum output capacitance of 20µF. The TPS51200DRCT supports a remote sensing function and all power requirements for DDR, DDR2, DDR3 and low power DDR3/DDR4 VTT bus termination. In addition, the TPS51200DRCT provides an open-drain PGOOD signal to monitor the output regulation and an EN signal that can be used to discharge VTT during S3 (suspend to RAM) for DDR applications.
1.1 to 3.5V VLDOIN Voltage range
Sink/source termination regulator includes droop compensation
Requires minimum output capacitance of 20µF (typically 3 x 10µF MLCCs)
PGOOD to monitor output regulation
EN Input
REFIN Input allows for flexible input tracking either directly or through resistor divider
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
