The Matek Micro BEC 5V/12V-ADJ is a compact and reliable power solution for a quadcopter. It delivers a stable 5V output at 1.5A, which gives consistent power to sensitive electronics.
The listing says it is built to perform in extreme conditions, with a wide operating temperature range of -45 to 85 degrees C, thanks to an integrated voltage regulator IC that maintains a constant voltage through the circuit.
The specification list gives selectable voltages of 5V, 9V and 12V, a standby current of 5mA and low output ripple, and the features mention an efficiency of about 95% and overheat protection.
Stable 5V at 1.5A: consistent power for sensitive electronics.
Adjustable output: 5V, 9V or 12V options.
About 95% efficiency: little heat and wasted power.
Overheat protection: helps protect the regulator.
Wide temperature range: -45 to 85 degrees C.
Low ripple: 20mV at 12V/1.5A and 40mV at 5V/1.5A (Vin 16V).
A BEC (battery eliminator circuit) converts the battery voltage to a lower, steady voltage for other electronics. A switching regulator does this by rapidly switching the input on and off and smoothing the result, which is far more efficient than a linear regulator when the input voltage is much higher than the output.
An adjustable BEC has a selector, usually a solder pad or jumper, that sets the output to 5V, 9V or 12V. Check the setting with a multimeter before you connect any device, because a 12V output will damage a 5V-only device such as a receiver or a flight controller.
Keep the input and output wires short, mount the regulator away from antennas and route the wires so that they do not run parallel to radio cables. Choose a BEC with some headroom over the current that the connected devices need.

The specification list gives 5V, 9V and 12V voltage ratings, a standby current of 5mA, a duty cycle of 0.95 and an output ripple of 20mV at Vin 16V and Vout 12V at 1.5A (40mV for 5V at 1.5A). The description gives a 1.5A output at 5V.
The page does not state the input voltage range or dimensions, so check the Matek datasheet for these before you connect a 6S battery.
