      Need to know WHO made it

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

          You need to know WHO made it before relying on on-line datasheets. If Fairchild makes it it'll take up to 35VDC input. If TI made it maybe up to 27VDC. For Linear, up to 25VDC. When pushing the input past 18VDC, quality heatsinks are MANDATORY, especially when using up to full current rating.

              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.

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

                    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!
