Xola asked I have a power supply with 5V, 12V and a varying output. The circuit I am supplying comparators, a PIC, etc?

The 12V output supplies the comparators (LM348 & UA741) and a relay. The 5V output supplies the PIC but as soon as I connect it, the power supply voltage drops even its AC input voltage. People say its a current problem but this circuit draws less 100mA when that voltage drop happens. My question how does this happen?

And got the following answer:

Are you trying to use to separate rectifiers from the same transformer winding (or taps on the same winding) to produce different voltages? Some power supply designs have multiple outputs but they are not independent - connecting the ground or negative from two outputs together effectively shorts the transformer windings via the rectifiers. Does the 5V side work OK if the 12V side is not connected at all? If so, the 5V circuit would seem to be OK and not drawing excessive power. Do you have appropriate voltage reduction circuits (eg. resistive dividers) between the 12V comparator outputs and the PIC inputs? With many CMOS or general logic ICs, if you 'force' current into an I/O pin by applying voltage outside the 5V (or 3.3v etc) logic supply range, you can make the whole chip substrate 'fire' like a thyristor and short the logic supply out. This usually also destroys or damages the chip... PICs are fairly rugged and you can use just a series resistor to limit input currents, but it's good practise to use a voltage divider to properly match the external voltage levels to the input pin logic thresholds. eg. a 10K from input to ground and a 15K from the 12V section to input would scale a 12V high level to 4.8V, safely within the 5V supply and still a good 'Logic 1' level. The 'low' level from such as a 741 is not always that low when on a single supply, it could be a volt or so, which is above TTL logic 'low' level. The divider also scales this down to have a better chance of it being seen as a logic low, anything up to 1.5V would still give a 'clean' logic low level, < 0.6V.
