The 9.6 volt regulator only supplies the receiver RF and the Exciter so a three terminal 9 volt regulator IC would work just fine. The three terminal regulator IC's are capable of up to 500 miliamps depending on the part number. And, the old 12 volt, and 9.6 volt, regulators are a VERY old design. Time to upgrade!!
