hello to all,
We are using power supply of PC to power our project which is Robotic arm. Can anyone please help me out that how can we step down the voltages (12V) to (6V). By using Buck converter it gets heated.
L7806 regulator is also a option but it drops the current. how to avoid this? I dont want to drop the current with voltage.
We are using 5 servos. so please suggest some easy ways. I’m totally lost
Hello @Tmalik,
I’m guessing you’re using a linear voltage regulator, these aren’t very efficient and convert the wasted energy [(12-5V)*current] into heat. You could try using a heatsink but I don’t think that will be enough. You should also read your voltage regulators datasheet in order to find if you need decoupling capacitors in your setup.
However, a better option would be using a switching regulator, which are more efficient (you can find the differences between linear and switching regulators here).
A good option would be:
But you can find many more options in the 5.0 V DC Regulators section of the store, that way you can choose one according to the current requirements of your setup.
I hope this information can help you out!

Hey thank you for help.
No I’m using a switching regulator not linear. But it’s not providing the 7.5 current output.
Can you please suggest any regulator which can step down the voltage from 12V to 6V. And also provide 7.5Amps in output.
As we require 6V for servos. Sorry forgot to correct it earlier.
Please suggest any easy way.
Then you should look into the 6.0 V DC Regulators section. By giving it a quick look I found this one:
You can find all its specifications here:
