XC6206P332MR 662K 3.3V 200mA TOREX LDO Voltage Regulator SMD SOT-23
The capacitors on Vin and Vout are not too close, maybe 1cm away from the pins, I've tried anything from 0.1uF to 22uf, Im powering the LDO from a 4.2 Lipo, It's the second LDO from a second supplier I'm trying.
Considering my input is DC, I'm a little confused why it's overheating. It appears to be drawing 200ma. Behaves the same with no load or if I connect a 1k resistor for some load.
I haven't tried an oscilloscope yet though to see if there's some instability. It is my first SMD circuit, I've used non SMT 3.3v regulators before without any issues.
Ordered and soldered two new 1uf ceramic capacitors as advised, did not change the outcome however. my caps could definitely be placed a lot better.
