Works a treat, buy several in case you blow one!
how do you wire them up?
Really easy, the link above has a tab for Downloads, click on that you get a datasheet, the datasheet shows it's a TO-220 package, and gives the pin numbers - IMPORTANT - do not get the the pin numbers the wrong way round, if you put power on the wrong way round the package can go bang and lots of little bits fly in every direction. Allegedly.
Bolt the chip to the bulkhead, metal to metal (I used a little heat sink paste) the middle pin is earth, solder a wire to this pin and bolt the wire to the bulkhead, remove any paint around the connection point. The middle pin is also connected to the metal rear of the chip, so you could
not bother connecting it, but belt and braces.
Pin 1, solder a cable to this (use heatshrink tubing to cover up the bare leg after soldering) and I used the input connection of the now defunct original voltage regulator as the feed.
Pin 3 solder a cable to this and it goes to the now defunct output cable from the original voltage regulator.
I've tucked mine under the original voltage regulator, used the original wires and connectors, so it's unseen and can be swapped back in seconds if anyone feels the need for the true original set-up.
