Hi,
I have a 5v 3amp reg, and I need the following supplies on my project
5v @ 200ma (max)
3.8v @ 2amp (max)
3.3v @ 200ma (max)
I currently use three regs to achive this the 3.3v & 3.8v being fed from the 5v reg. (saves smoothing caps and three wide voltage range regs)
Could I use voltage dividers instead of the 3.3v & 3.8v reg bearing in mind that the current drawn from the 3.8v device varies from a few ma to 2amp. and the 3.3v device stays pretty much constant at 120ma
P.S. Main supply is 12v-24v (vehicle / truck)
Thx
