Let's say I want to make a 3D printer main board

LMR51450SDRRR - Voltage regulator [1] TPS2116DRLR - Power source selector [2] TXS0108ERGYR - Logic voltage translator [3] LM61495RPHR - Voltage regulator [4] LP5912-3.3DRVR - Voltage regulator [5] Those are all some kind of voltage regulators I found in SmartPrintCoreH7x [6] open source main board. And those are not all. It seems to me
