Adjust output of U3V40F5 to be 5.1 or 5.2 V?

I have several U3V40F5 5V step up regulators and I was wondering if it is possible to tweak the output of these to be slightly higher than 5V to provide a little bit of headroom in the projects I’m using them in?

I’m assuming there are certain resistors that set the output value of these regulators. I wanted to know which resistors I need to swap and what should I swap their value to in order to get 5.1 V and 5.2 V.


It is possible to increase the output voltage of the U3V40F5 regulator by changing some of the surface mount resistors on the board as you mentioned. If you are interested in trying it, please email us for more details.


Thanks, email sent.
