NCP51403 Termination Regulator

NCP51403 3 Amp VTT Termination Regulator DDR1, DDR2, DDR3, LPDDR3, DDR4 The NCP51403 is a source/sink Double Data Rate (DDR) termination regulator specifically designed for low input voltage and low noise systems where space is a key consideration. The NCP51403 maintains a fast transient response and only requires a minimum output capacitance of 20 mF. The NCP51403 supports a remote sensing function and all power requirements for DDR VTT bus termination. The NCP51403 can also be used in .
