Building a Linear Power Supply, Part 4 A Precision Regulator

A non-precision regulator allows a small voltage drop when the load increases. A precision regulator holds the voltage more steady.

Very interesting video, thank you.

Very clear and helpful, thank you.

Thank you soo much sir for this lesson

[@amarmail8033]

I need a good power supply. wanted to make myself to save money. I dont have to do the experiments now. Thanks a lot.

I always find it useful and informative ❤

From 24:20 it's like an eye operation!

Nice. Are you going to cover current regulation?

>> Could this be a good Tip..: ,,Run Zener's (in all cases of sizes /zenerVoltages) to around 20mW - 60mW. ,,Say fex.. '30-mW' (milli-Watts). _One could in addition put in a current-source driving (for this case, trough this 6v2-zener) 5 milli-Amps trough the Zener. ,,-->No need to run Zeners towards their socalled 'max-specs'. //Thanks for interesting videos and good content.

In addition to running the Zener at a sensible current choose a 5v1 Zener as these usually have a near zero temperature coefficient. Lower voltage Zeners have an increasingly negative temperature coefficient and higher voltage Zeners have an increasingly positive temperature coefficient.
