NCP51401 Termination Regulator

Pin Number Pin Name Pin Function 1 VRI VTT External Reference Input ( set to VDDQ / 2 thru resistor network ). 2 PVCC Power input. Internally connected to the output source MOSFET. 3 VTT Power Output of the Linear Regulator. 4 PGND Power Ground. Internally connected to the output sink .

3 Amp VTT Termination Regulator DDR1, DDR2, DDR3, LPDDR3, DDR4 NCP51401 The NCP51401 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 NCP51401 maintains a fast transient response and only requires a minimum output capacitance of 20 mF. The NCP51401 supports a remote sensing function and all power requirements for DDR VTT bus termination. The NCP51401 can also be used in .
