The some models of holographic dark energy for Randall-Sandrum brane are considered. For first class of dark energy models we take energy density in form $\sim L^{ 2\gamma-4}$ where $L$ is size of events horizon in Universe and $\gamma$ is parameter (Tsallis holographic energy). Analysis of observational data allows to define upper limit on value of $\delta=\rho_{ 0}/2\lambda$ ($\rho_{ 0}$ is current energy density in the Universe and $\lambda$ is brane tension). Then we investigate models for which dark energy density has form $\rho_{ de}=C^{ 2}L^{ -2}-C_{ 1}^{ 2}H^{ 2}$ where $H$ is Hubble parameter.
