will putting five volt regulators in parallel reduce the strain on them? Answered
I'm using a peltier plate and some CPU fans to make a micro fridge for my car. for testing purposes, I'm going to need a pretty beefy power supply. because the plate draws four watts at twelve volts, I need a supply that can push out around three and a half to four amps. however, I don't want to go out and buy something, because I have a very limited amount of money. what I do have, however, is a large amount of leftover twelve volt regulators from an earlier project, rated to work with up to one amp. will connecting several of these in parallel (maybe five of them, just to be sure) be enough to reduce a thirteen and a half volt power supply with 3.9 amps of current to twelve volts? this is the closest I can get to a twelve volt supply with the materials I have, and I already have a heatsink for the regulators (I tore apart a dead computer power supply).
