i am now in the process of choosing a suitable linear regulator for my project which is a RF LED Dot Matrix Display. My LED Board has input requirements of 5V and 2.4A.
I actually intended to use the LM2678 switching regulator because of high efficiency for the project but my supervisor said that it would be too highly efficient for a simple LED board like that..(like using a whole power station to power one single light bulb) and the cost would be excessive ( converted from my country's currency, the regulator will cost approximately $5 which is kinda high for my supervisor) and so I am now searching for a suitable linear regulator.
I would really appreciate if anyone could recommend me any linear regulator (as well as the link to its datasheet ) suitable for my project which is cheap and meets my project input requirements.
