I want to use the S9V11F5S6CMA to take Voltage of around 4 V-10 V from my Solarpanel in and give out 5V to power the TP-4056 to charge li-ion batteries. It works when it’s not connected to the two TP-4056s that are connected in parallel (work correctly via USB and worked a number of times by just pressing VOUT and VIN of the Regulator against + and - of the TP4056s). However, usually the Voltage drops to a stable 0.88V and stays there until I try to solder something on VOUT and suddenly it’s back to 5V (Perhaps the heat causes some kind of refresh?). I have no idea what I’m doing and I don’t want to damage the regulator… I hope somebody can help me
What I forgot to mention: The Input voltage measured on the regulator is also at just around 2.33 V when it gives out 0.88 V. It should instead be at least around 4-5 V.
