Default FBT-00-031 voltage reg

Hi,

I have a couple of Lambda power supplies that I'm fixing. One has dead voltage regulator chip, Lambda part number FBT-00-031, apparently made by Motorola in the early 90's. It's a 14 pin DIL, but it's NOT a uA723 (at least it looks like it has a completely different pinout). In later units this was replaced by an FBT-00-034, which should be a functional equivalent.

I have a test data sheet from Lambda.

Does anybody by chance have a few of these left or knows a source that doesn't ask for 300 $ min order...?

Thanks in advance,

Jan Didden

I did receive a quote. Ridiculous; this is a chip that cost a few dollars 10 years ago. They try to make a killing from obsolence.
