LE33 DATASHEET PDF

Daidal Or can I leave the 2. Sometimes they also specify how much resistance the capacitor should have, called ESR: Which satasheet strange because the test circuit on the datasheets really shows the black rectangles. I bought a couple of LE33 voltage regulators which finally arrived today. The value of 4. Smaller ones help reduce high frequency oscillation. The size of a capacitor will vary depending on the maximum voltage it supports.

Bakora Or can I leave the 2. But when I went to the local Electronics shop, the guy at the shop showed me a 2.

Are my humidity sensors faulty? 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. 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. Reply Quote 0 1 Reply Last reply. In fact, it depends a lot on your power source For example a batterie usually delivers clean power compared to a cheap phone charger.

Sometimes people have used both! This part is very much dependent on the specific regulator. 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. You may just have to test, and see how reliable the radio is. How to hookup a LE33 This topic has been deleted. And he said that I would need an electro capacitor. As a result, your viewing experience will be diminished, and you may not be able to execute some actions.

The value of 4. The size of a capacitor will vary depending on the maximum voltage it supports. It would be nice if someone could draw a simple circuit. Only users with topic management privileges can see it. Reply Reply as topic.

Which is strange because the test circuit on the datasheets really shows the black rectangles. Why are the measured values so different? If so which ones and how the I connect them. There is no specified size tho. Loading More Posts 6 Posts. These caps should be close to the regulator to help keep it stable. You might not even need it Smaller ones help reduce high frequency oscillation. I bought a couple of LE33 voltage regulators which finally arrived today.

Your browser does not seem to support JavaScript. 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.

Larger ones help keep the voltage steady during spikes in the current used by the radio. An Esp Nextion Scene controller?? Erratic battery reading when powering via RAW pin.
