Overview
The TPS51200DRCTG4, 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 consideration. It maintains a fast transient response and requires a minimum output capacitance of only 20 μF, making it highly efficient for memory termination applications.
