I got a few diodes from DVD.
I want to make a simple driver with TTL modulation.
I know that the red diode need 2.5 volts, but the store I found lp2985 3 volts.
I know that the diode current is important, but lp2985 may issue a maximum of 150ma. What should save diode from burn?
lp2985 has input on / off http://www.ti.com/lit/ds/symlink/lp2985-n.pdf
Whether it is suitable as a modulation ? :thinking:
3 volts converted to 2.5 probably can be delivered to a resistor in parallel?
Thanx.
