I have a input dc voltage range of 3V to 4.2V (Input).
Design looks like this: Input(3-4.2V) -> Boost -> LDO -> 4.3V or lower
Edit:- Closer the output voltage of LDO to 4.3V(but not more than 4.3V) better it is, since it will give better adc resolution, have adc reference 4.3V actually.
Need to get 4.3V or lower at the output. LDO is used to remove switching noise for measuring sensitive analog signals.
Entire ckt is battery powered so low power is required. Can you suggest some suitable solution for this?
