Hello!
Recently, I have made a lot of small projects, which include MCU (ATTINY13a) with some inputs (reading frequencies, digital signals) and sometimes outputs (LEDs, output BJT). As far as projects being successful, I am wondering, why is this type of power supply nowhere to be found on the web? Everyone seems to be using linear regulators such as LM7805 for that kind of projects. Well probably I just don't know the right keywords to find it.
I have attached my power supply schematics, which is working fine. Can you give me some cons and pros for ''my'' power supply and linear regulators? I am aware that this power supply will not handle much current. Also, which one is preffered for this kind of projects and why? Most of my projects are used in automotive. Does this kind of power supply produce a lot of noise for other electronics attached to same ground line (if more than 5 power supplies of this type are used in the same car)? I have also attached simple project for frequency detection (so you see where this power supply is being used as example).
Thanks in advance!
