As I rolled my simpleified (removed the overload protection circuit) home-built PMOS LDO circuit on a breadboard, I found out something strange is going on.
Now what is going on? Why am I seeing 0.01 V across my 1 kΩ load? Also, why is the sampling voltage divider emitting 0.04 V? Or is it because of the OPA2134 amplifier? Did I get a fake one from the Shenzhen supplier?
Am I treading the waters of leakage currents of semiconductors?
