Linear Voltage regulator with 1% or better accuracy over industrial temperature range

I'm looking for a linear voltage regulator 0.5A output @ 5.0Vdc, accuracy needs to be +/-1% or better over entire industrial temperature range. Input voltage will be between 12 and 24Vdc.

Prefer the simplicity of a 7805 style regulator, with better accuracy. Does such a component exist, and if so part #?

And if not, circuit suggestions for improving the accuracy of a 7805 style regulator?

Thank you

You'll have to use an external reference, which will provide feedback to an adjustable regulator.

There was a Linear Tech app note where they outlined the use of an external reference and a LM317-type regulator.

Hi,

Go to manufacturers homepage and use selection tools.
I just tried TI and it gave more than 15 hits.
Try TLV1117.

klausST,

I found the same part using TI's selector. This looks ideal, and inexpensive as well. I'm going to go with it.

Thank you.
