Hi everyone, I have a timer circuit that is going to power my arduino micro and a relay. I am going to run the 555 output to a 7805, or 7806 reg. The nominal relay current is 120ma, and the Arduino is 22ma running code. Do I need to need to run a transistor between the 555 and the 7805, Or will the 555 output be sufficient for the voltage regulator. I have some TIP32AJP PNP power transistors 3A TO_220, but in my case, the smaller footprint is better. Not sacrificing reliability, but not over kill either. Here is the circuit, I'm sure someone will recognize it. Thank you
