the circuit in the post "useful circuit" i posted a few days ago has a error in it. the output lead should go to the output leg and the other end of the resistor should go to the adj leg of the regulator NOT the way round it is on the pdf. bryans circuit is correct. thought it looked wrong but went ahaed and tried it. yep it was wrong.

Makes no sense to post this here where nobody will ever see it and no link to the original, post to the original where it will be useful.
