I could ask AI, but let's see what we Humans have as thoughts on this.
I need to raise the output voltage of the 78M05 regulator about 0.5 to
0.8VDC by adding a 1N400X diode in series with the ground pin to common. The problem is voltage drop between the regulator and the old logic board because the wire is around 2' (60cm).
Any reason I SHOULDN'T do this? Nothing in the data sheet about this, they want me to use a pair of resistors...
Looking for a very SIMPLE way to advise customers a very easy and reliable way to raise the voltage about 0.5 - 0.8VDC. Current draw is around 1A or less. Input voltage to reg is around 12VDC. I don't want to use a pair of resistors because it needs to be very simple for barely capable customers. The case is isolated from Common already. A diode is optimum because if it shorts then the CD output simply drops to 5VDC, instead of rising to the supply voltage if the connection to ground opened...
Any other one part solutions that a person with minimal soldering skills can do?
My X-Files reference book is at home and I just came up with this possible solution at the shop...
Thanks!
