I need a LDO, not switcher
Vin=21V or 22V
Please let me know if you have any suggestions.
I suggest the LM317.It is an adjustable regulator; two resistors will be needed to set the output voltage to 18V.

There is also the LM317M.
Last August we released the TPS7A4901 which is a 36V tolerant Linear Regulator. Here is the link : http://focus.ti.com/docs/prod/folders/print/tps7a4901.html
Let me know if you have any questions. This is a very high, wide bandwidth Linear with very low noise.
