(With Respect to 12V ofc.)
.............................................
I plan on using a LM317 (or LM7812) to power the 555 and the Driver. Im going out on a limb to say it probably wont need more than 1 amp, but even 1 amp is a lot. However, it can only be used for a differential voltage of up to 40V. Can I just use a Simple Series Pass Voltage regulator to lower the voltage before the LM317? (or LM7812). The only circuit I can find is this document (
www.ti.com/lit/an/snoa648/snoa648.pdf). To me all it looks like is what I proposed. Nothing complex. I think I would get rid of R3, since I dont need a current limit.
