Re: Best way to get 2.5 volts from somewhere? (Vcc = 5 volts)




I have a question...

If I have an LED that has about 2 volts across it, then is it OK to
put a 2 volt power supply across it without a current limiting
resistor?

My overall power supply would be 9 V coming from a square battery, but
I'll be putting it thru a voltage regulator to give me out 2 V.

I'll then be putting the 2 V across the LED.

Can I leave out the LED's current-limiting resistor, or is there still
a chance of there being too much current that would fry components?
