7.4v output from 12v supply help
Posted: Mon Feb 06, 2017 1:01 am
Hi all.
I need to get 7.4v output from 12v input. I have some 7809 regulators and a schematic to get this from 12v to 9v, but I need 7.4v to run a Canon camera on my telescope. Is it a case of fitting a resistor of some size, and if so, where would this go (I presume after the final capacitor and before the output socket), and what size resistor would I need? Any advice is greatly appreciated.
Thank you.
