          Comments about RadioShack® +12V Fixed-Voltage Regulator 7812:

          This Radio Shack 7812 works just like a 7812! Seriously folks... I've been using these chips since the 70s. The ones you buy at Radio Shack are _exactly_ like you'd buy anyplace else. Not cutouts or inferior product that were culled from production, They're just, well, 7812s. Radio Shack didn't invent them or manufacture them. The specs are the same as they've been for over 40 years. There is a _lot_ more information than RS could or should provide. It's called a datasheet. Look up the datasheet for a TI chip and then one for a Fairchild cip. Read the datasheets if you want to figure why your circuit is blowing it.

          Comments about RadioShack® +12V Fixed-Voltage Regulator 7812:

          When using less tham 0.1 amps it had good performance. At 0.15 amps it went totally bad and let the voltage soar.

            The most useful things in a technical product include actual useable specs and data, not what COLOR it is and that it can "support" English.

                Don't complain about a data sheet. It is all over the net. input ground output. Pretty straightforward. They WILL withstand 18 volts if it is filtered and a heatsink is used.If it failed it wasn't the part!
