P2P solution for ISL80101IRAJZ in DFN10

Hi LDO team, 

Could you help to check if you have a P2P solution for ISL80101IRAJZ in DFN10? 

https://www.renesas.com/us/en/document/dst/isl80101-adj-datasheet

We are looking for a voltage conversion from 5V to 3.3V with up to 1A of load. 

But for Vin, we would need the input be able to tolerate up to 40V abmax. 

Do we have something that would fit the need here? 

Thank you, 

Jason Song

    Hey Jason, 

    We do not have anything p2p with this device. If 35V abs max would be okay for Vin I would recommend the TPS7A47. If not the LM317 would work well here. I gave some additional options to look at if the Vin max is able to be lowered for this. In functionality the TPS7A94 would be the closest to this part, but not able to meet to meet the Vin range requirements for this.
