Figure 2-6 TPS51200A-Q1 Functional Block Diagram

The TPS51200A-Q1 device is a sink and source double-data-rate (DDR) termination regulator specifically designed for low input voltage, low-cost, low-noise systems where space is a key consideration. The device maintains a fast transient response and only requires a minimum output capacitance of 20μF. The device supports a remote sensing function and all power requirements for DDR, DDR2, DDR3, and low power DDR3 and DDR4 VTT bus termination. In addition, the device 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.
