ALYW The NCP51401 maintains a fast transient response and only requires a minimum output capacitance of 20 F. The NCP51401 supports a remote sensing function and all power requirements for DDR V bus TT 51401 = Specific Device Code termination. The NCP51401 can also be used in lowpower chipsets A = Assembly Location and graphics processor cores that require dynamically adjustable L = Wafer Lot output voltages. Y = Year W = Work Week The NCP51401 is available in the thermallyefficient DFN10 = PbFree Package Exposed Pad package, and is rated both Green and Pbfree.

RI TT DDQ 2 PV Power input. Internally connected to the output source MOSFET. CC 3 V Power Output of the Linear Regulator. TT 4 P Power Ground. Internally connected to the output sink MOSFET. GND 5 V V Sense Input. The V pin provides accurate remote feedback sensing of V . Connect V to the TTS TT TTS TT TTS remote DDR termination bypass capacitors. 6 V Independent Buffered V Reference Output. Sources and sinks over 5 mA. Connect to GND thru RO TT 0.1 F ceramic capacitor. 7 EN Shutdown Control Input. CMOS compatible input. Logic high = enable, logic low = shutdown. Connect to V for normal operation. DDQ 8 GND Common Ground. 9 P Power Good (Open Drain output). GOOD 10 V Analog power supply input. Connect to GND thru a 1 4.7 F ceramic capacitor. CC THERMAL Pad for thermal connection. The exposed pad must be connected to the ground plane using multiple PAD vias for maximum power dissipation performance.
