dropping diode
Hi
I am building a circuit to be powered by 3.6V. Except one part can only take 2.7-3.3V.
Can I use a diode from the +3.6V rail to the VCC of that part ? Diode would have say 0.7V drop, so would provide 2.9V to part.
Part is SPI interface. I could also use same diodes for the SCK and MOSI lines. MISO would go from part to controller, so that would not need dropping diode.
That would work ?
Thanks.
