NCP51510 3 Amp V Termination TT Source / Sink Regulator for DDR, DDR-2, DDR-3, DDR-4 The NCP51510 is a source/sink Double Data Rate (DDR) termination regulator specifically designed for low input voltage and NCP51510 PIN FUNCTION DESCRIPTION Pin Number Pin Name Pin Function 1 V OUTPUT Buffered Output of V Reference Input pin. RO RI 2 V INPUT Regulator Analog Power Input pin. Connect to the system supply voltage. Bypass V to A CC CC GND with a 1 F or greater ceramic capacitor. 3 A Analog Ground GND 4 V INPUT External Reference Input for V Output (see Figure 1 for typical application) RI TT 5 P OUTPUT V Power Good pin (open drain output) GOOD TT 6 V INPUT Remote Sense Input for V . The V pin provides accurate remote feedback sensing of the TTS TT TTS V output. TT 7 SS INPUT Suspend Shutdown Control Input. CMOS compatible. Logic HIGH = enable, logic LOW = shutdown. Connect to VDDQ for normal operation. 8 P Power Ground. Internally connected to Lowside MOSFET GND 9 V OUTPUT Regulated Power Output pin TT 10 PV INPUT Regulator Power Input pin. Internally connected to Highside MOSFET CC THERMAL Pad for thermal connection. The exposed pad must be connected to the ground plane using multiple vias PAD for maximum power dissipation performance.
