DESK OF LADYADA - STEMMA Sunday + Low Power Evening - The Great Search: Ultra low quiescent 3.3V reg

Every Sunday we work on a new STEMMA QT board - this week we made one for the MCP9601 - an I2C capable thermocouple sensor. This is one of the only I2C thermocouple AFE's we've seen, and we've already got a library for the earlier MCP9600. (The MCP9601 adds open-thermocouple detection!) We also worked on the Feather M4 CAN - with Arduino and CircuitPython support nearly wrapped, its time to finish the hardware. We have a few changes we made to reduce the power draw and got down to 250uA in sleep mode....but could we go lower? The Great Search: Ultra low quiescent 3.3V regulator https://www.digikey.com/short/zdhjqf To make our new Feather design low power friendly, we're going on a hunt for a replacement of the AP2112-K 3.3V regulator. Hear why we love the AP2112 and also why we have to find an alternative - can we find one that's close-to-drop-in compatible??
