Switching UBEC?

A normal BEC just takes in the input voltage and cuts it in two parts. One for the receiver at the appropriate voltage, and the rest is turned into heat.

A switching BEC is better, it switches on or off depending on what it needs - it doesn't heat up.

Switching is better but usually found in bigger ESC's, 40A up for example.
