Hello forum,
First, I must admit, I didn't do a search on the forum on my topic since I just don't have a clue for a keyword...
Now, my problem is this: I want to take a digital signal 0-3V and convert it to 0-5V or 0-2V (by changing the supply from 5V to 2V) using transistors (I can't really find an IC, and I only need 2 input/outputs and then a 14pin IC is too space demanding on my board).
I have come up with the circuit shown below.
It needs to be able to handle a bit of current, like 25mA on the output (sink/source).
The problem is, it shorts the supply.
What am I doing wrong?
If you by chance know a common IC with 2 inputs/outputs with a voltage range of 2-5V, please let me know. Thanks.
Regards,
Futterama
