Components for TXv3

Hi.

I'm buying components for my EmonTX v3, but I'm having trouble finding some components.

1) In the BOM list (http://wiki.openenergymonitor.org/images/EmonTx_V3.2_BOM.png), what's the current for L1 component? (Ferrite bead)

2) MCP1700 is listed as SOT22, but I just could find as SOT-23. Is that right (SOT-23)?

3) MCP1754 is listed as SOT89 package, but I could only find MCP1754S as SOT89. Is this right? If yes, which one is the right model? MCP1754ST-5002E/MB, MCP1754ST-3302E/MB or MCP1754ST-1802E/MB?

 

Thank you!
