The FPGA(XC3S1500) on the board needs 1.2v, 2.5v and 3.3v power supplies, and the config PROM needs 1.8v. The ARM7(LPC2106) on the board needs 3.3v and 1.8v supplies.
Can I use 6 mic29502 (a LDO regulator) chips to transform 5v power to satisfy all these 6 power demand? If I make a mistake, please help to supply a new scheme.
Thanks in advance!

Power Management : TI Power Management Solutions for FPGAs

Texas Instruments offers easy to use power management solutions for powering the latest high performance FPGAs. Powering an FPGA can be challenging since the power consumption depends upon the clock frequency, toggle rates, routing, I/O power, and resources used. TI has developed useful tools to simplify the selection of the power management solution and address concerns such as in-rush current and voltage ramp rate requirements.

Remember that FPGA current consumption is like burst mode, so use good low ESR cap.
I do have experience with TI for FPGA board so I agree with - dainis go to
TI power management solutions for FPGAs.
