Hi, I'm building a simple board with Spartan IIE ( XC2S100E), and wondering is it OK to derive power for VCCINT (1.8V) and VCCO (3.3V) from something simple, such as LM317. I know it can source enough current during start-up, but I'm not sure about voltage ramp, power sequencing etc. Any hints are welcome. Thanks in advance, Goran
