There is no connection diagram for EP in the datasheet. We are using an LDO (Part Number: LT1121ACS8-5#PBF) to convert the supply voltage for the L9825 (+24V to +5V), and we are providing the L9825 with +5V as a power supply. LDOs have a common ground for +24v and +5v side. Should the EP be connected to the ground or the supply voltage?
