LM2937: Recommended ADJ equivalent device

Hello,

I would like to replace a 12V version of the LM2937 with an equivalent LDO with an adjustable output since it is undecided whether we will need 15V or 18V output in the final design. It does not need to be pin-to-pin compatible, but it does need at least a 26V input rating, at least 400mA output, and can work with the same input/output capacitors currently used with the LM2937. I'm also looking for a SOT-223 package due to height restrictions. Any help would be appreciated.

Thanks
