That’s definitely possible, or the HT7333-A doesn’t meet the specs in its datasheet. I’ve swapped the LDO out for a 500mA one on two boards now, but will experiment with other boards that still have the 250mA one in place.
Can you share more details on your solar powered air quality monitoring system? Mine is still a work-in-progress, but I’ve already open-sourced it here: GitHub - OpenAirMonitor/OpenAirMonitor: Main repo for the OpenAirMonitor
