Hi, I’m using a D24V150F5 5v regulator to power a bunch of servos. I also have a smaller separate 5v regulator for the microcontrollers. I would like to power up the D24V150F5 as disabled rather than enabled by default. Is there a way to swap out the pull-up for a pull-down resistor instead? Or is it possible to add a pull-down over the pull-up, and then be able to drive that high still with a 3.3v microcontroller?
The pull-up on the EN pin is internal to the regulator IC and cannot be removed or changed, but you could add an external pull-down to overpower it. Something between 10kΩ and 100kΩ should work fine.
