Introducing the RMRC 5v/12v Step Down Regulator!
The high efficiency, low noise regulator accepts up to 6S voltage input, and provides filtered 12V and 5V output at 1.5A max per channel. It's perfect for powering most FPV gear, and also powers your receiver on multirotors with “Opto” ESCs, eliminating the need for an external BEC.
Note that the 12V regulator does not boost the voltage. However, the RMRC Step Down Regulator has a unique Low Voltage Loss feature that drops the regulator’s output by only about 0.5V if you are using a 3S pack operating below 12.5V. For example, if your 3S pack is at 11.5V, the regulator outputs about 11V. Other non-boost switching regulators typically drop the output voltage by 1.3V or more.
