NCP51400, NCV51400
3 Amp VTT Termination
Regulator DDR1, DDR2,
DDR3, LPDDR3, DDR4
The NCP51400 is a source/sink Double Data Rate (DDR)
termination regulator specifically designed for low input voltage and
lowânoise systems where space is a key consideration.
The NCP51400 maintains a fast transient response and only requires
a minimum output capacitance of 20 mF. The NCP51400 supports
a remote sensing function and all power requirements for DDR VTT
bus termination. The NCP51400 can also be used in lowâpower
chipsets and graphics processor cores that require dynamically
adjustable output voltages.
The NCP51400 is available in the thermallyâefficient DFN10
Exposed Pad package, and is rated both Green and Pbâfree.
