Good video. Thank you for your effort to share your knowledge. An often overlooked specification of the LM78xx series of linear voltage regulators... While 2 volts of headroom is the typical voltage needed to prevent dropout, =>3 volts is necessary for the device to achieve its best ripple rejection factor. The trade off is obvious, better rejection verses more heat.
Temperature and Ripple would have been neat to have on the chart. I wonder how older electronics and 8bit computers would handle the ripple, or if adding some output caps could clean it up enough not to matter.
This is a great tutorial thanks ! I think the 7805 is safe for now as the Recom device is handy and has some definite advantages but will remain quite niche as the price is £5.61 which i guess is about $7 ?.....I had forgot about them and are worth considering, once again cheers !
You are quite right about the price, you could get dozens of the 78XX for the cost of one 78E. The price in the US is about $3.50 for the 5V variety. I'm surprised they cost more in the UK, Recom is a German company if I am not mistaken. Thanks for watching.
