TPS73633 max current is 400mA. Around 250mA @ 50°C ambiant temp.
MCU + MicroSD max consumption is a bit more than 100mA ( I don't remember the exact numbers we measured)

Guys, it’s a great work! Congratulations!

However I’m a bit confused with Apogee power solution. The STM32F4 and SD card are on the same 3,3V power line… Won’t a small SOT23 linear regulator chip be a bit thermal overloaded, for example in a thermal isolated planes body in hot weather?

Best Regards,

Sergey
