24v to 5v
Hi! someone can tell me a circuit that makes me go from 24v to 5v?

Use 7805 Voltage regulator IC
By changing the Resistance R you can vary the output from 5 V to 24 V.
if you don't want to Vary the Out put Then shot the Center Pin to the Ground.
1 Amp is the maximum for this IC
Sanalece,
That is a particularly poor way to jack up the output of an LM7805. The current that flows out of the GND pin is a stong function of temperature, the input voltage, the phase of the moon, etc.
The better way is to use a LM317 with a voltage divider (two resistors) to set the output voltage. If you have to use 7805, then the voltage divider upper resistor must be like 100Ω so that the current out of the GND pin is a small fraction of the total current that flows down the divider...
The circuit is bad no matter what the current requirement. The OP hasn't responded to the question regarding current, nor to the ambiguous voltage.But let me ask you one thing, What is the current requirement Here ?
I mentioned the circuit is for 1 Amp maximum usage, it is enough for that, Much complicated then we can have much functionality....! Let the Needer replys We will C then........!
I've been using the 7805 for a long time. A very long time. We appear to differ on the definition of what a good and proper regulator should do.
The author told me that it's crap.Hi, Friend - Who is here speaking about a regulator Char....s... I know what a regulator - But Understand one thing that, what the author of this post says, let us wait for him.....
OP logged off ten minutes after posting the question and has not returned. All we know is he probably has 24V and might want 12V or maybe 5V at some unknown current, if any. We have been answering each other with the usual result.
