V Low Dropout Voltage regulator mA LE33CZ | ST Microelectronics

Zeph and rvendrame thanx for claryfing things. Which is strange because the test circuit on the datasheets really shows the black rectangles.

Erratic battery reading when powering via RAW pin. Sometimes people have used both! An Esp Nextion Scene controller??

The size of a capacitor will vary depending on the maximum voltage it supports. Because I wasn’t able to find it on the forum. You might not even need it You may just have to test, and see how reliable the radio is.

Anyway do I need any capacitors? At the moment I’ve setup a lot of sensors on lr33. Your browser does not seem to support JavaScript.


You may need to play a bit with values to find the best cap for your situation. There are a potentially a couple of related issues involved here, regarding caps.

The value of 4. Reply Reply as topic.


I have been looking on google for hours, but I can’t find an example of how to connect them. So I have a question. These caps should be close to the regulator to help keep it stable. I bought a couple of LE33 voltage regulators which finally arrived today.

Are my humidity sensors faulty? Please download a browser that supports JavaScript, or enable it if it’s disabled i. Reply Quote 0 1 Reply Last reply.

3.3V Low Dropout Voltage regulator 100mA LE33CZ

This part is very much dependent on the specific regulator. Larger ones help keep the voltage steady during spikes in the current dztasheet by the radio. I’ll just have to build up a test circuit on a breadboard. I asked if he couldn’t order them any smaller. Or can I leave the 2.

Sometimes they also specify how much resistance the capacitor should have, called ESR: 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. Smaller dafasheet help reduce high frequency oscillation.

I want to use them to power my antenna’s directly from a 5V power adapter.

And he said that I would need an electro capacitor. There is no specified size tho. I’ll start with adding the 2. But when I went to the local Electronics shop, the guy at the shop showed me a 2. The specs of the LE33 are very promising, so I’m hoping to get this to work. 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.

If so which ones and how the I connect them.
