Please download a browser that supports JavaScript, or enable it if it’s disabled i. I’m still learning on the electronics. So I have a question. I bought a couple of LE33 voltage regulators which finally arrived today. I want to darasheet them to power my antenna’s directly from a 5V power adapter.

I have been looking on google for hours, but I can’t find an example of how to connect them.

The test circuit on the data sheet says that I have to use a 0. But when I went to the local Electronics shop, the guy at the shop showed me a 2. I asked if he couldn’t order them any smaller.

And he said that I would need an electro capacitor.

Which is strange because the test circuit on the datasheets really shows the black rectangles. Anyway do I need any capacitors? If so which ones and how the I connect them. It would be nice if someone could draw a simple circuit.

Because I wasn’t able to find it on the forum. The size of a capacitor will vary depending on the maximum voltage it supports. I’m not really sure if I understand this part correctly, but if I connect a 2. Or can I leave the 2. The value of 4. You may need to play a bit with values to find the best cap for your situation.

In fact, it depends a lot on your power source For example a batterie usually delivers clean power compared to a cheap phone charger. You might not even need it Voltage regulator chips often specify input and output capacitors, partially to reduce the ripple, but also sometimes in order to keep the voltage regulator internal circuitry stable.

For the latter purpose the regulator manufacturer often specifies capacitor size perhaps a range. Sometimes they also specify how much resistance the capacitor should have, called ESR: This part is very much dependent on the specific regulator.

These caps should be close to the regulator to help keep it stable. There is no specified size tho. Larger ones help keep the voltage steady during spikes in the current used by the radio. Smaller ones help reduce high frequency oscillation. Sometimes people have used both! One to smooth high frequencies, one for low frequencies.

You may just have to test, and see how reliable the radio is. Keep the wires to the radio short; if you cannot, the cap close to the radio becomes more important, even if you have one on the regulator output. Zeph and rvendrame thanx for claryfing things.

I’ll just have to build up a test circuit on a breadboard. I’ll start with adding the 2. The specs of the LE33 are very promising, so I’m hoping to get this to work. At the moment I’ve setup a lot of sensors on breadboards.

Why are the measured values so different? Are my humidity sensors faulty?
