But when I went to the datashest Electronics shop, the guy at the shop showed me a 2. Sometimes they also specify how much resistance the capacitor should have, called ESR: I’ll just have to build up a test circuit on a breadboard.

In fact, it depends a lot on your power source For example a batterie usually delivers clean power compared to a cheap phone charger. 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.

3.3V Low Dropout Voltage regulator 100mA LE33CZ

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. The specs of the LE33 are very promising, so I’m lle33 to get this to work. You may just have to test, and see how reliable the radio is. So I have a question.


The dafasheet of a capacitor will vary depending on the maximum voltage it supports. At the moment I’ve setup a lot of sensors on breadboards. Which is strange because the test circuit on the datasheets really shows the black rectangles.

This part is very much dependent on the specific regulator.

If so which ones and how the I connect them. I asked if he couldn’t order them any smaller. For the latter purpose the regulator manufacturer often specifies capacitor size perhaps a range. You might not even need it Only users with topic management privileges can see it. I bought a couple of LE33 voltage regulators which finally arrived today.

The value of 4. I want to use them to power my antenna’s directly from a 5V power adapter. There are a potentially a couple of related issues involved here, regarding caps. An Esp Nextion Scene controller?? It would be nice if someone could draw a simple circuit.

Reply Reply as topic. One to smooth high frequencies, one for low frequencies. You may need to play a bit with values to find the best cap for your situation. Because I wasn’t able to find it xatasheet the forum.


I have been looking on google for hours, but I can’t find an example of how to connect them. I’m not really sure if I understand this part correctly, but if I connect a 2. As a result, your viewing experience will be diminished, and you may not be able to execute some actions. Erratic battery reading when powering via RAW pin. How to hookup a LE33 This topic has been deleted. Larger ones help keep the voltage steady during spikes in the current used by the radio.
