Power headroom.

headroom for higher current. The device has four RGB channels, so the power dissipation will be up to 4 × ((4.2 – 3) + (4.2 – 2.7) + (4.2 – 2.1)) × 0.01 = 192mW. If you go as high as 20mA and use only one regulator for all colors of 5V (which is available as fixed output voltage) the power dissipation is even higher.The invention relates to a method for transmitting power headroom information from a user equipment to the base station.
