I have a project where I need to drop voltage by exactly 1 volt. +/- no more than .05v.
The hang up is this has a varying electrical demand, varying temperature, and varying voltage. And it needs to be responsive - if the voltage is changing quickly, this too needs to change quickly.
This IS a DC application with a voltage range between 11 and 17v, and the current draw of <500ma.
I've toyed with diodes but those only create a drop of .7v. And resistors don't do well with fluctuating current demands. Plus I'll have variances in temperature between about 0 degrees and 175 degrees Fahrenheit. I've been banging my head against the wall trying to come up with a way to do this but I'm just not getting anywhere.
Ideas?
Trying to explain the project I'm doing would be tough and it's not really pertinent. So I'm going to say don't worry about it
