Voltage RegulatorsIC7 is a Texas Instruments TPS75003 triple-output regulator. The regulator provides 1.2Vto the FPGA’s VCCINT supply input, 2.5V to the FPGA’s VCCAUX supply input, and 3.3Vto other components on the board and to the FPGA’s VCCO supply inputs on I/O Banks 0,1, and 2.

Jumpers JP6 and JP7 provide a means to measure current across the FPGA’s VCCAUX andVCCINT supplies respectively.

IC8 is a Linear Technology LT3412 regulator, providing 2.5V to the on-board DDR SDRAM.Resistors R65 and R67 create a voltage divider to create the termination voltage requiredfor the DDR SDRAM interface.

IC9 is a 1.8V supply to the Embedded USB download/debug circuit and to the CPLD’sVCCINT supply input.
