No, wait, I'm just looking at this https://ww1.microchip.com/downloads/aemD...05399B.pdf
Simple Voltage Regulator ....

What do you think?

You have the choice: archaic and simple (resistor + zener diode) or more parts for a boost converter. NE555 is not bad for that. The MC34063 would be a terrible choice...
The "Simple Voltage Regulator" from your datasheet link is a linear regulator which will produce the same amount of heat as the archaic solution.
