Low quiescent linear Voltage Regulator
The TPS7A6601 has 12uA typical (20uA max) Iq, and can withstand 45V for 200ms. Pretty close. 

Or make a high dropout/high voltage linear pre-regulator using a MOSFET voltage follower and one of the many low-Iq LDO CMOS regulators that can't handle high input voltage.
