We refer to the following different types of regulators:
Burgos: The regulators of Borel and Beilinson. Available online somewhere
Ramakrishnan: Regulators, algebraic cycles, and values of L-functions (1989)
See Goncharov in K-theory handbook.
Kuzmin has several papers with something like “remarks on the l-adic regulator” in the title. One is from 2009 in Izvestiya

Have gone through a MathSciNet search on regulator AND cohomology
