Arduino 5V regulator is too hot
i've car proyect arduino needs arround 550mah, arduino 5v regulator hot, can pololus heat sink solution?
best regards.

what powering arduino from, 12vdc car's dc jacks , plugging arduino through barrel connector?
what powering requires 550ma?
if regulator getting hot, i'd separate dc/dc converter provide power instead of getting heat sink. while heat sink may help, still run risk of regulator shutting down (especially if inside of car hot on summer day example). not mention arduino uses linear regulator, output voltage decrease draw more current. here's switching step-down dc/dc converter can give 12v input, , provide steady 5v output 600ma. 600ma max current close 550ma, double check actual current draw is.
