Am I reading this data sheet right?
Read times previous topic – next topic. If I am not correct, would there be an easy way to get a solid 5v out of this thing no matter what the main output voltage is? I understand it is tough without a schematic, I will get one up as soon as I datashest. There is no way!

To my understanding they should have used V0 rather than Vz in the first place But this is a quite versatile regulator with a lot of options. However it willl provide one voltage only!
The pic on their site is old, there is most certainly a on-board Here’s the kit that I have along with a pic of the schematic. A picture of the parts list is below.
It sounds like my best bet would be to include a second regulator in the box, perhaps just a small wall-wart tied to the v input hooked with a or similar to provide the 5 volts. There is also a 24vAC transformer in the box as well Take datasheeg that you have to establish a common ground when you tap the same transformer with a different rectifier It would be better to tap directly at C1 if possible. How much current do you want to draw 5V?
Not much at all Enough for a small cooling fan and a single red 25mA power status led. So you need not really stabilized voltage at all!
At C1 you will have an untidy DC I should guess around 30V, dropping when you have some amps load at the end. As they do not stabilize, you will have 5 to 6V eventually, this can be mended by an additional 1N C1 is the smoothing datxsheet on the output of the bridge rectifier ; it is not AC as you claim.
This is the correct location for your providing that the voltage across C1 is within the rating of the input. I haven’t looked up the spec sheets but I think you might be exceeding its capability with an expected DC level of around 40 volts. You might be trying to over-design things. If all the LED is doing is showing a supply then why not just use 2k2 resistor straight ca723cr the C1 voltage.
You should use a series resistor in the input of the regulator, say ohms rated at 2 watts to save the regulator having to do all the work and it’ll also act to reduce the input voltage of the regulator.
As I’ve said, my electronics knowledge is pretty much all self taught. According to the schematic I am in the process on transferring it to eagleC1 is connected to ground and the AC input through the 4 diodes is this the bridge rectifier you mention? If I can just get away with a few series resistors to handle things, that would be fabulous. Here is an eagle schematic and a link to the eagle file itself to make things easier.
So this is no solution The voltager across C1 is unregulated rectified DC. This is quite a load. If you want to go this route then use a resistor rated at least 10 watts and have the fan blowing air over it. You’d be much better off looking for a miniature 12 volt fan which will draw a lot less current. The series resistor required will then be of much lower wattage. Even better would be a 24 volt fan but these will be harder to find.
Sounds like my best best would be a small wall wort adapter as what deSilva mentioned It would be fairly small, simple to wire up and stable read:
