PIN FUNCTION DESCRIPTION
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 MOSFET.
5
VTTS
VTT Sense Input. The VTTS pin provides accurate remote feedback sensing of VTT. Connect VTTS to the
remote DDR termination bypass capacitors.
6 VRO Independent Buffered VTT Reference Output. Sources and sinks over 5 mA. Connect to GND thru
0.1 mF ceramic capacitor.
7 EN Shutdown Control Input. CMOS compatible input. Logic high = enable, logic low = shutdown. Connect
to VDDQ for normal operation.
8
GND
Common Ground.
9
PGOOD
Power Good (Open Drain output).
10 VCC Analog power supply input. Connect to GND thru a 1 − 4.7 mF ceramic capacitor.
THERMAL Pad for thermal connection. The exposed pad must be connected to the ground plane using multiple
PAD
vias for maximum power dissipation performance.
