NCP51400MNTXG

NCP51400MNTXG 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. It maintains a fast transient response and only requires a minimum output capacitance of 20F. It supports a remote sensing function and all power requirements for DDR VTT bus termination. It can also be used in low-power chipsets and graphics processor cores that require dynamically adjustable output voltages. The applications include DDR memory termination, desktop PCs, notebooks, and workstations, servers and networking equipment, telecom/datacom, GSM base station, graphics processor core supplies, set-top boxes, LCD-TV/PDP-TV, Copier/Printers, chipset/RAM supplies as low as 0.5V, active bus termination. It can also be used in low-power chipsets and graphics processor cores that require dynamically adjustable output voltages.
