Don't forget to factor the forward drop of the SS diodes into the equation. Factor the drop in before you multiply RMS by 21/2. Use Schottky diodes, whose forward drop is approx. 0.5 V., in the bridge. Even then, a low dropout regulator is in order.
Approx. 1/2 the RMS current is available as DC, when cap. I/P filtration is employed. You said 1.5 A. RMS is available. So, you are good to go, with 600 mA. of DC being needed.
