    A: Hi Peter, You can run the amp kit from as little as 2V, however the higher the supply the better the quality. As such powering from a 9V supply you would be able to attach the regulator without an issue. You would take the positive supply from the amp kit and connect this to the input on the regulator, the ground would be the negative from the amp and also to the negative of the module. The output from the regulator would then be connected to the positive supply on the module. This should work without a problem, however to smooth any spikes out you could connect a 100nF capacitor across the input and ground connection as well as the output and ground connection.

    There are a range of fixed voltage regulators that will give you 5V at a higher current, such as the MC7805CT. Unfortunately our range of ICs is designed to allow students to do simple GSCE projects and as a result we don’t have a range of regulator ICs. I can only suggest searching on 5V fixed voltage regulator and you should be able to find some options.

    Best regards
