L6925/6/8 regulator

Hi all,

Does anyone happen to have a spare ST Microelectronics L6925, L6926 or L6928 regulator in an MSOP8 package?

It's to try to repair a friend's GOP XC3S200:

The regulator is meant to generate 1.2V, but is currently generating 2.9V :shock:

It seems the output MOSFET is short-circuit. Suffice to say, the FPGA soon gets quite hot (but seems to still work).

It may be this is a lost cause, as the FPGA may have suffered long term damage, such as partial breakdown of the gate dielectric.

The only supplier I can find is digikey:

but they want £12 shipping on a £2 part!

Somebody might have one, but if they don't...

I'm going to place a Mouser order this week. If this is suitable I could tack it on and either stick it in an envelope to you or bring it to the meeting the weekend after next.
