Building a Cave Dweller with a Taptation circuit, and when I plug in my 9V DC, the 78L05 regulator gets really hot!
I really want to check the voltages on the whole circuit to debug it, but I'm scared to keep the power plugged in.
What's wrong with it? Did I do some bad soldering to make it happen?
EDIT:
Switched in another regulator, same thing happened
Are you feeding it 9v?
Check to make sure it's in the right orientation. Also the diode and cap.
Otherwise you must have a short or bad joint nearby.

Wrong orientation, the layout I used used a different regulator, thanks! But now new problems...

Glad you sorted it. Yes, 7805 and 78L05 are different...done that a few times myself.
