The EV kit operates from an external 2.8V to 5.5V power supply applied at the VIN and GND PCB pads. The MAX5389 operates from a 2.6V to 5.5V VDD supply. Additional LDO regulators are provided to operate the MAX5389 VDD input at 2.6V or 3.3V. The on-board regulators require a 200mV overhead above their respective outputs.
