I have a buck converter whose output varies from 4.8V to 5.2V. This buck converter is present in my VCU. Input for the buck converter can vary from 8V to 14V.
The 5 volt rail is powering many IC's present on the board, and for those IC's, this 4.8V to 5.2V is fine and there are no issues.
The same output from this buck converter is provided as a reference voltage for the vehicle's throttle.
Since the output of the buck converter is varying, the throttle output also varies, which is not acceptable.
What circuit can I use to generate a constant 5V from this varying 4.8V to 5.2V buck output?
