I want to make a regulator to stabilise the vehicle battery supply (in a camper van) to between 11 to 12v max to run LED lighting..I've got coming from Ebay a few low drop out LM2940CT-5.0 5v regulators - because they were cheap, and plan to use them with 6v2 zeners in the common terminal to make 11.2volts supplies. (slightly underunning the LEDs deliberately)
My question is are there disadvantages of doing it this way as opposed to buying 12v versions so far as chip performance is concerned ?
Thanks
