LM335A: Similar part in a smaller package.

Part Number: LM335A
Other Parts Discussed in Thread: TMP235-Q1, LM45, LM50-Q1, LM61, LMT90, LM50, TMP235

Can you recommend a similar style device that comes in a smaller SMT package?  SOT-23, SC-70, etc.  SO-8 is pretty big, TO-92 is big and thru hole.  

I don't want any digital parts or one that has low current like a TMP36.  I need to pull some current through it.  1mA+.  

I also need options if this part goes obsolete so I need a backup plan.  Speaking of that, any plans to retire this device?

Thank you,
