This is the second CLT20 title for the IPL 6 winners, having won the 2011 edition.
Chasing a massive 203-run target, Royals folded for 169 even after a fabulous start that saw them scoring 100 runs in nine overs.
Tendulkar and Royals skipper Rahul Dravid, both of whom having announced quitting the T20 game after Sunday's match, were out for low scores.
