2011年1月25日 · 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?

2023年10月3日 · 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?

2013年4月17日 · Hi Everyone I am looking for the spice model for the LM7805 voltage regulator

2019年8月9日 · 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 …

2012年3月19日 · Hello, Can anybody help me run this simulation of LM7805. it is suppose to give 5V of clean output. i have to charge 5V battery from it. Thanx

2015年11月14日 · One possibility I'm wondering about is if the lm7805 requires a minimum current, and the solar panel isn't meeting some minimum current requirement. Is that even a …

Please understand that i am actually a really beginner in electronics. I found a really nice topic on how to create a 5V DC from a 9v power supply. All is ok. But in order to smooth out ripple, the

2020年12月25日 · 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 …

2020年5月1日 · I am a novice who purchased several TO-220 L4940v5 chips thinking they were drop-in replacements for the inefficient TO-220 7805s that I've been using. But not a single …

I'm using an LM7805 in voltage regulator mode. Vin is 15V Vout is 5V (regulated) The attached load draws 200mA How to calculate how much power the LM7805 would dissipate in this …
