Pololu 5V, 5A Step-Down Voltage Regulator D24V50F5


#1

Hi,

I’m designing something with D24V50F5 but I don’t want it to be enabled through the internal pull-up resistor it has. Is it possible to remove the resistor manually?

Hello, zygan.

I circled that pull-up resistor in the picture below. You can remove it to stop the regulator from being enabled by default… Once you remove the resistor you should make sure that the EN pin is always being driven high or low when the regulator is powered to avoid the pin being in an undefined state.
