I need a 5V voltage regulator with no fancy regular-mode electrical requirements. The load current will be below 10mA, efficiency is not a concern and I can provide sufficient headroom -- assume 8V is the minimal Vin. The only special need here is its ability to survive harsh conditions at its input. At the typical 12V V_in with +40V followed by
-40V spikes would be nothing extraordinary. While technically I can find devices with similar ratings, I would like to get a practical advice. Would you kindly name your indestructible faves? I can go discrete as well -- a Zener powered by a depletion-mode MOS with a 200V Schottky in series is an option, but if there is a SOT23-like single part that would do the job, why not...
Best regards, Piotr
