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. I want to use them to power my antenna’s directly from a 5V power adapter. In fact, it depends a lot on your power source For example a batterie usually delivers clean power compared to a cheap phone charger.

I have been looking on google for hours, but I can’t find an example of how to connect them. You may need to play a bit with values to find the best cap for your situation. I’ll start with adding the 2. Which is strange because the test circuit on the datasheets really shows the black rectangles.

Smaller ones help reduce high frequency oscillation. You might not even need it 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. I bought a couple of LE33 voltage regulators which finally arrived today.


Datwsheet 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. Zeph and rvendrame thanx for claryfing things. Erratic battery reading when powering via RAW pin.

At the moment I’ve setup a lot of sensors on breadboards. As a result, your viewing experience will be diminished, and you may not be able to execute some actions.

Sometimes people have used both! I’ll just have to build up a test circuit on a breadboard. And he said that I would need an electro capacitor.

These caps should be close to the regulator to help keep it stable. Or can I leave the 2. Your dattasheet does not seem to support JavaScript. I’m still learning on the electronics. There is no specified size tho.

V Low Dropout Voltage regulator mA LE33CZ | ST Microelectronics

Anyway do I need any capacitors? Why are the measured values so different? The value of 4. So I have a question. The size of a capacitor will vary depending on the maximum voltage it supports.

Only users with topic management privileges can see it. The test circuit on the data sheet says that I have to use a 0.


For the latter purpose the regulator manufacturer often specifies capacitor size perhaps a range. I datadheet if he couldn’t order them any smaller. But when I went to the local Electronics shop, the guy at the shop showed me a 2. There are a potentially a couple of related issues datawheet here, regarding caps. Please download a browser that supports JavaScript, or enable oe33 if it’s disabled i.

You may just have to test, and see how reliable the radio is. Are my humidity sensors faulty? Loading More Posts 6 Posts. If so which ones and how the I connect them. I’m not really sure if I understand this part correctly, but if I connect a 2. The specs of the LE33 are very promising, so I’m hoping to get this to work.

Sometimes they also specify how much resistance the capacitor should have, called ESR: One to smooth high frequencies, one for low frequencies. Reply Reply as topic. It would be nice if someone could draw a simple circuit.

How to hookup a LE33 This topic has been deleted. This part is very much dependent on the specific regulator.
