Hi, I'm interfacing a gps board and a radio module with a ATxMega128A1U, everything works fine apart that doesn't start!!
What is happening is that when supply power the micro goes on reset in loop.. Basically the gps and radio board fro a fraction of time is pulling down the voltage and the micro goes in reset, due to the brown detector. the chip im using is a LM2595 3.3 I though that a 220uF cap to the out put would have hold that fraction of time the charge until the voltage is stabilized, but eventually not! So does any one how to get around of this thing i mean without using another regulator.. an other chip.. I have attached a photo of the power supply schematic.
thanks
