Hi, I've run into a problem that I have worked on for quite a while. I was trying to find an inexpensive way to drop a 2-36V source down to around 1-1.5V. I had done it with a zener and a LDO voltage regulator before to drop sources from 5-18V, until I found a particular source that had 36V. I had been using the zener to drop the higher voltages down to a range that my voltage regulator could handle. However, when I tried the same circuit on the 36V source, the zener drew too much current causing the source circuit to "misbehave". The source is a DC source and the less current I draw to drop it down the better. The source isn't a battery and has some output impedence (which is why I used the zener), but depending on the product I test on, the voltage varies between 2-36V.
Is it possible to do this inexpensively? I am not an expert by any means but have done the best I can researching on my own and trying my own solutions. Any help is much appreciated.
