4.4 No Load Start-Up at High Output Voltage

The LMR12020 cannot start-up at no load when the output voltage goes above 3.3 V. Refer to the LMR12020 data sheet for more information regarding minimum load requirements. A position for a dummy load is provided on the board. Populating that with a 500-Ω resistor facilitates the start-up at no load for the 5-V output voltage options.
