I want to come up with a circuit that is powered from USB that I can use for multiple devices with a microcontroller on-board. Mainly having to do with sensors.
* Analog to digital converters using 5 volt reference.
* Digital to analog converters using 5 volt reference.
* Amplification circuits using multiple op amps that are powered from 5 volts (as well as -5 volts coming from a charge pump), and using 5 volts with a voltage divider to get an accurate amplification.
These are some examples. As you can see, an inaccurate 5 volt reference will lead to inaccurate sensor readings.
