12V TO3-style regulator available

The PSU6 is similar to the LM323 replacement in shape but produces 12V at 1A.  Since the TO3 package is no longer manufactured all the regulators in this package will disappear from the market in due course.

PSU6 next to its older brother


The PSU6 has a 40V absolute maximum input voltage and will produce 1A without a heatsink.  It is mechanically identical to a LM7812K and is more accurate being within 2% of 12V under all load and input conditions.  It includes over current, thermal and short circuit protection.

One of  the improvements made to to the PSU6 based on user feedback is that the rings around the ground contacts have been increased in size.
