I ordered it at small local company Kohout Spoj. For filtering of rectified voltage there are C1 and C2.

So my senior project is due Thursday and because of my extreme wits and knowledge I accidentally connected A Voltage dqtasheet the incorrect way because I was unwary of the different pin-out. Next we continue with connectors, transformer and big capacitors.

Possibly also available in a “variety bag”. The 79L series are mA regulators in TO packages. Transformer in this package datasgeet a lot of manufacturers.

I tried to design them symmetrically. R1 is a 2W power resistor and could be made from combining other values. It allow to create it in a amateur conditions.

At uA load, you won’t need a heatsink. I also posted the link to the website in my first comment. The diode droppers in your circuit, at low currents will not drop the supply voltage below 35 volts.

Now bridge satasheet these two secondaries individually and then use two to create regulated and isolated two 12V supplies. Spehro Pefhany k 4 So my local radioshack has a ina they sell it in a pack of two could I use these 2 in series and therically have double the current capacity?

So, given the above, there is a strong case for assuming the regulator is undamaged and therefore reusable. Daatasheet format Eagle6 format.

Connect the positive of the two leads to your ground, and the negative will be your V supply. If this is just for a short demo, then you may be able to use a few batteries. I cannot be sure but over-driving at maybe 37 or 38 volts is a good reason you destroyed it. If voltage on the big capacitors will be under Darasheet am Basically building the power supply scene here kerrywong.

You didn’t post your circuit. Well there’s your basic problem – the absolute maximum input voltage you can put on a is 35 volts – if you have 36 volts on the output then you’ll likely have even more on the input side.

If your negative regulator is blown and you need a quick fix, replace the whole thing with a off the shelf datasheeg V power supply. Something like this should suffice for a quick setup.

You could build something similar if you don’t need high performance. Is there any common household objects that have a or equivalent that someone may know about?

Circuit description Circuit has on the primary side only fuse. If it’s only for a reference voltage with a very small current, maybe the shop has a 79L24 absolute max. We can also use 2 pin connectors for LED connecting. We must also check allowed voltage of capacitors. Schematics diagram schematics in Eagle 6 format Assembling First we check if all holes are correctly drilled. Andy aka k 10 When we use LEDs with a small current 2mA that we can use bigger resistors about 1k5. Almost all components are usually available.

Output voltages are connected to 3 pin connector. I went to radio shack and they did not have any regulators. I Just feel guilty doing that for all they judges know who I am presenting to I could just Put a in there and say look it works and stuck a bunch of wires in there and they would be beyond impressed:
