Dec 7, 2009 · How do most voltage regulator ICs work? Are they the same as hooking up a variable resistor and a voltmeter and turning the knob until you get the desired voltage?

May 22, 2025 · I wish to build and get 3.3 V from LM7805 voltage regulator with some extra parts like resistor and maybe a Zener diode. How can I achieve that, is it even possible to do that?

Oct 3, 2023 · How can I use the LM7805 regulator in LTspice? I know it's about importing the third party components, but I am not getting it. Can somebody help please?

Aug 9, 2019 · 8 I read in the LM7805 datasheet that I can change the output voltage to not only 5 V, but to another value by changing the circuit resistance. How do I do that? From what I understand, to …

May 28, 2020 · 1 I am using a LM7805 linear voltage regulator. Vin is 12 V Vout is 5 V (regulated) My load is currently 100 mA. Without a heatsink, it's pretty hot. Could i use a large heatsink to regulate 5 …

I find the above answers not appropriate. Here's what I think: The Capacitor on the input : It is used to eliminate the electrical noise in case the sub unit containing this regulator IC is at a distance from the …

Jul 10, 2022 · Then take the output 15 V from the middle and feed it to LM7805 input. Not capacitors: they'll charge as you describe, but then you'll just immediately drain the charge from the bottom …

Dec 25, 2020 · Hi there. I've been playing with a gate opening device that runs on an ESP32 wireless device. Its working fine. It is being powered from a 12V car battery via an LM7805 voltage regulator …

Dec 29, 2021 · What's an LDO? It's an improved linear regulator that allows a much smaller overhead voltage than earlier regulators like the LM7805. Overhead voltage is the same as dropout, which is …

Mar 10, 2022 · I have a 12 volt power source which powers an LM7805 regulator, in order to power a circuit board. If I were to accidentally connect the power source backwards (reverse polarity,) which …
