Add to S-Manual SMD Code
I have a SOT23-3 IC which acts as an LM432 or TL432 Programmable Precision Shunt Regulator
It is marked 3HU with H with a line on top of it. It has the standard 2.5V volt reference and acts exactly like that chip.
Another shunt regulator that acts the same way is the HA17431VLTP from Renasas.
There are a lot of marking codes for this IC reference but this is another one.
