You will be hard pressed to get under that cost. Seems to be about what the market will bear. 


That said, you might focus a little on "automotive grade". While the temperature range may be wider than you need, they are built to handle input up to 35V or more. And, the are priced a bit more aggressively. There are also a number out, now, in some variation of SOT-23. They are still fairly easy to work with yet small and cost seems strongly related to total volume of the part.

Subject: [AVR-Chat] Buck regulator 






I'm looking for recommendations for a low cost buck regulator, input could 
be as high as 20VDC, output 3.3V at <= 100mA Efficiency is less important 
than cost, SMD package. 

I've only been finding parts up around $0.70 in 100k quantities and that 
seems kinda crazy high given what it does. 

Suggestions?
