AFAIK lineair regulators are bad at that.

Regulating the voltage to “exactly” 5volt under various loads, sure. Most of them its jumping between 4. I believe my draw to be mA so I’ll feed it with 7.

The size of these will be in the data datxsheet for the exact device and manafacaturer you are using, do not use a generic data sheet. It is easy to miss the decimal point without a leading zero. DaveEvans God Member Posts: I’ve been looking at a load of youtube videos.

I agree, it may be a measurement issue. I assume the output one is ceramic.

How odd they specify that on the datasheet! I’ve been using the hoary old LM for decades. Reading throught the first post, I see that the OP wants to remove the “ripple”.

That high frequency blows straight through a slow device like that. Are they required and if so what size datssheet least possible ripple?

This is because these capacitors can fail short circuit and cause a fire. Mylar is fine but expensive.

Yes caps are essential on both sides to reduce the supply impedance. Russel once again thank you. Ive seen a number of implementations of the L circuit which use caps on the input and the output. Therefore the project will go: If you try that in a design you want to pass UL it will fail.

While waiting for the postman to deliver my parts I just wanted to see how other peoples experiences panned out: Now with Unlimited Eagle board sizes!

But for HF ripple removal use capacitors LC circuits and ferrite beads. Wawa Shannon Member Posts: Just interested as Ive never used these before to find out if the 4. Retired after 40 years as a chartered engineer working mostly with RF and analogue electronics.


Ah you know how it is russel. I don’t actually require LDO but 2v is low enough for my modest needs. I’ve never seen one that unstable!

Right at the limit works – but if the input drops, so will the output. Or there are some noisy digital loads and insufficient bypassing.

Apologies for my error. Using a tantalum capacitor across a power input here is bad. Page 25 of the datasheet shows a 33uf cap on the input and a 0. I have an Ultimaker and a 3D engraver. My final question is this. Test equipment, replica and original sci fi props and costume pieces, and whatever else I feel like at the time.

Granted they all seem to show standard ‘s but they voltage isnt as stable as i’d like to see. Always write it 0. I missed the decimal point.

Hi Grumpymike, Firstly apologies.
