Almost all components are usually available. Connect collector to negative input supply. Next we continue with connectors, transformer and big capacitors. Read the data sheet.

Pin 1 for the is the most positive pin i. If it’s only for a reference voltage with a very small current, maybe the shop has a 79L24 absolute max.

I have a few 2n transistors laying around would that work?

I tried to design them symmetrically. Your transformer must be center tapped 24V type, commonly denoted as 12,0, Circuit description Circuit has on the primary side only fuse. 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.


What I mean by split the power supply at the transformer secondary is to actually split the center tap carefully to make 12, 0 and another 12, 0. Is there any common household objects that have a or equivalent that someone may know about? Now connect them in series and take the center tap as your common ground. So my senior project is due Thursday and because of my extreme wits and knowledge I accidentally connected A Voltage regulator the incorrect way because I was unwary of the different pin-out.

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: The users who voted to close gave this specific reason: Your problem solved without need to have the For signaling of presence of voltage 779l12 enough only one LED. Connect emitter to the V output.

Something like this should suffice for a quick setup. I cannot be 7l912 but over-driving at maybe 37 or 38 volts is a good reason you destroyed it. I ordered it at small local company Kohout Spoj.

We begin with resistors, small capacitors, leds, regulators, fuses and rectifier. I also posted the link to the website in my first comment. D1 is a 13V 1W Zener and could be made up from some combination of zeners in series. The 79L series are mA regulators in TO packages. Next are small filter capacitors and also signaling LEDs connected via resistors. Output voltages are connected to 3 pin connector. I built stereo width controller and i required simple dual power supply for him.

Surplus and obsolete components – Voltage regulators

For filtering of rectified voltage there are C1 and C2. It doesn’t matter on the assembling order. Next are positive and negative voltage regulators 78L12 and 79L12 with decoupling capacitors C3 to C6 close to regulators. So, given the above, there is a strong case for assuming the regulator is undamaged and therefore reusable. Board is designed single-sided.

If this is just for a short demo, then you may be able to use a few batteries.
