You can keep the settings at 5V. LDO is really for drop out, giving you an interrupt when power fails. This will give you the chance of shutting down some IO-pins to a safe state, so that the 30t crane stops before hitting the wall.
thanks a lot.
I meant that I'm introducing an external LDO to keep the PSoC 5LP Power Supply stable to 4.5V.
Is the same? Can I keep the settings at 5V?
Oh, sorry, I misunderstood you. Set the voltages to the real-world 4.5V. This will affect internal oscillator stability and the ADC conversions when you are using VDD as reference.
I'm using an external quartz, and for ADCs I'm using External Vref generated by PSoC5LP with a PGA (fixed 1.024V multiplicated 2 as gain). The input range of ADCs is "0.0 to 2.048 (Single Ended) 0 to Vref*2.
In this case do you think could be any "Side Effectes" ?
Thanks and regards

There are some more relying on that setting. Measure internal chip temperature and flash programming, bootloading ... I do not yet see why you hesitate to set the voltages as they really are...
Thanks Bob, I've understood. I going to set the voltages to 4.5V.
Thanks a lot
