These regs have dropped greatly in price. We used to pay +$20 each for something like this, now they are less than $2, for a 5V 1A reg with max 32V input. They come in various voltages too.
A good way to save power and heat.
They are pretty small!
No heat sink needed either.
It will be interesting to see how noisy they are.
