Sometimes people have used both! It would be nice if someone could draw a simple circuit. You may just have to test, and see how reliable the radio is.

How to hookup a LE33 This topic has been deleted. There are a potentially a couple of related issues involved here, regarding caps.

I’m still learning on the electronics. I’ll just have to build up a test circuit on a breadboard. If so which ones and how the I connect them. This part is very much dependent on the specific regulator.

In fact, it depends a lot on your power source For example a batterie usually delivers clean power compared to a cheap phone charger. Which is strange because the test circuit on the datasheets really shows the black rectangles.

For the latter purpose the regulator manufacturer often specifies capacitor size perhaps a range. I want to use them to power my antenna’s directly from a 5V power adapter. Only users with topic management privileges can see it.


Keep the wires to the radio short; if you cannot, the cap close to the radio datahseet more important, even if you have one on the regulator output.

Erratic battery reading when powering via Dahasheet pin. Zeph and rvendrame thanx for claryfing things. As a result, your viewing experience will be diminished, and you may not be able to execute some actions.

How to hookup a LE33 | MySensors Forum

I bought a couple of LE33 voltage regulators which finally arrived today. Why are the measured values so different? But when I went to the local Electronics shop, the guy at the shop showed me a 2.

Voltage regulator chips often specify input and output capacitors, partially to l33 the ripple, but also sometimes in order to keep the voltage regulator internal circuitry stable. At the moment I’ve setup a lot of sensors on breadboards.

Anyway do I dayasheet any capacitors? I asked if he couldn’t order them any smaller. The specs of the LE33 are very promising, so I’m hoping to get this to work. The size of a capacitor will vary depending on the maximum voltage it supports.

3.3V Low Dropout Voltage regulator 100mA LE33CZ

Loading More Posts 6 Posts. You may need to play a bit with values to find the best cap for your situation.


I have been looking on google for hours, but I can’t find an example of how to connect them. Sometimes they also specify how much resistance the capacitor should have, called ESR: Reply Reply as topic. There is no specified size tho. These caps should be close to the regulator to help keep it stable. I’ll start with adding the 2. You might not even need it One to smooth high frequencies, one for low frequencies.

The test circuit on the data sheet says that I have to use a 0. The value of 4. I’m not really sure if I understand this part correctly, but if I connect a 2. Your browser does not seem to support JavaScript.

Smaller ones help reduce high frequency oscillation. Reply Quote 0 1 Reply Last reply. Or can I leave the 2.

Larger ones help keep the voltage steady during spikes in the current used by the radio. Please download a browser that supports JavaScript, or enable it if it’s disabled i. An Esp Nextion Scene controller??

Because I wasn’t able to find it on the forum. Datashdet he said that I would need an electro capacitor. So I have a question. Are my humidity sensors faulty?
