Smaller ones help reduce high frequency oscillation.

Sometimes people have used both! I’ll just have to build up a test circuit on a breadboard. Your browser does not seem to support JavaScript. If so which ones and how the I connect them.

Erratic battery reading when powering via RAW pin. 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.

At the moment I’ve setup a lot of sensors on breadboards. One to smooth high frequencies, one for low frequencies. I’ll start with adding the 2. I have been looking on google for hours, but I can’t find an example of how to connect them. I bought a couple of LE33 voltage regulators which finally arrived today. You might not even need it Voltage regulator chips often specify input and output capacitors, partially datasheeh reduce the ripple, but also sometimes in order to keep the voltage regulator internal circuitry stable.


Only users with topic management privileges can see it. For the latter purpose the regulator manufacturer often specifies capacitor size perhaps a range. The value of 4. 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 may just have to test, and see how reliable the radio is. This part is very much dependent on the specific regulator. Why are the measured values so different? So I have a question. An Esp Nextion Scene controller?? Sometimes they also specify ,e33 much resistance the capacitor should have, called ESR: And he said that I would need an electro capacitor.

Reply Reply as topic. I’m still learning on the electronics. The specs of the LE33 are very promising, so I’m hoping to get this to work. The test circuit on the data sheet says that I have to use a 0. Which is strange because the test circuit on the datasheets really shows the black rectangles.

Reply Quote 0 1 Reply Last reply. You may need datasheett play a bit with values to find the best cap for your situation. The size of a capacitor will vary depending on the maximum voltage it supports. There are a potentially a couple of related issues involved here, regarding caps.

There is no specified size tho.

I’m not really sure if I understand this part correctly, but if I connect a 2. Or can I leave the 2. But when I went to the local Electronics shop, the guy at the shop showed me a 2.

Anyway do I need any capacitors? These caps should be close to the regulator to help ddatasheet it stable.

It would be nice if someone could draw a simple fatasheet. I want to use them to power my antenna’s directly from a 5V power adapter. Zeph and rvendrame thanx for claryfing things.

Are my humidity sensors faulty? I asked if he couldn’t order them any smaller. Please download a browser that supports JavaScript, dwtasheet enable it if it’s disabled i.

Larger ones help keep the voltage steady during spikes in the current used by the radio. Because I wasn’t able to find it on the forum.
