I'm building a project that will be powered from a 24VDC wall wart which will power a solenoid. I need to step this down to 5VDC at 10 mA for my logic. The circuit will be implemented on 25 - 75 simple PCBs I'll be hand-assembling, probably using through-hole components. I'm looking for a power supply circuit that's simple, reliable, and cheap. I've been leaning toward a voltage divider or Zener diode, but thought I'd see if the community has some better ideas, or suggestions/caveats regarding these two approaches. Thanks.
