For signaling of presence of voltage is enough only one LED. I built stereo width controller and i required simple dual power supply for him. First we check datashete all holes are correctly drilled.

Surplus and obsolete components – Voltage regulators

The diode droppers in your circuit, at low currents will not drop the supply voltage below 35 volts. Output voltages are connected to 3 pin connector. That’s a negative regulator. Spehro Pefhany k 4 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.

Circuit has on the primary side only fuse. We can connect power cord directly to the X1 connector or via power switch on the chassis.

Connect the positive of the two dztasheet to your ground, and the negative will be your V supply. Your problem solved without need to have the The 79L series are mA regulators in TO packages. I am Basically building the power supply scene here kerrywong. We assemble parts from a smaller to bigger.

We must also check allowed voltage of capacitors. Now connect them in series datashete take the center tap as your common ground. Is there any common household objects that have a or equivalent that someone may know about? I understand this is a long shot but I really need this part my project will not work without it.

Board is designed single-sided. Your transformer must be center tapped 24V type, commonly denoted as 12,0, R1 is a 2W power resistor and could be made from combining other values.

Next are small filter capacitors and also signaling LEDs connected via resistors. It doesn’t matter on the assembling order. If it’s only for a reference voltage with a very small current, maybe the shop has a 79L24 absolute max. I went to radio shack and they did not have any regulators.

D1 is a 13V 1W Zener and could be made up from some combination of zeners in series. The users who voted to close gave this specific reason: You could build something similar if you don’t need high performance.

Dual power supply

If this is just for a short demo, then you may be able to use a few batteries. Andy aka k 10 It allow to create it in a amateur conditions.

Component view Printed circuit boards Board is designed single-sided. 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: 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 have a few 2n transistors laying around would that work? And for a quick fix just so it works tomorrow this might work correct? PDF format Eagle6 format. Home Questions Tags Users Unanswered.
