I made myself a little clone of this board here https://flashcandy.us/big-nugget-v1.html
Mostly to teach myself KiCad and Hotplate SMD soldering. It seemed to work fine at first but then I noticed the voltage drop under load. It's set to output 5.1V but when I put a 5 Ohm load on it it drops to 4V. The battery voltage and the VSYS voltage remain stable so I suspect the MIC2876 but its datasheet has pic related and I'm basicly using it like the Typical application describes. Anyone got a clue what might be wrong?
