The ESP32-C3 has an unofficial requirement: the 3.3V rail must rise monotonically. V3 used a basic AP2112 LDO with a 10µF ceramic on the output. The problem? The LDO’s soft-start interacted with the high-Q ceramic cap, creating a "step" in the voltage ramp. The C3’s brownout detector would randomly fire.

: Steps down raw voltage from the lithium-ion cell safely to values under 1.2V for core computational engines.
