Hello.
I have a question about LT3081.
The LT3081 has an absolute maximum rating of ±40V from Vin to Vout.
In addition, the feature section is 1.2V to 36V.
For example, if the potential difference from Vin to Vout is within 40V, is it possible to generate 40V from 45Vin?
Best regards
Hi. The LT3081 is capable of arbitrarily high output voltages, but as Alexxx mentions, you need to be careful about start up and faults. We don't have a reference design of arbitrarily high output voltages for the LT3081, but the LT3090 datasheet has a reference design that shows the idea and I show that in the image below. The LT3090 is a negative LDO and has a GND in that can attach to OUT, but the same idea of clamping with zeners can be applied to the LT3081 with no GND pin.
