I need a LDO, not switcher

Vin=21V or 22V

Vout=18V

I suggest the LM317.
It is an adjustable regulator; two resistors will be needed to set the output voltage to 18V.

Hi Angela,

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.

Regards,

John
