Notes:

Note2: As input approaches output voltage set point, device enters 100% duty cycle mode. In 100% duty cycle

mode, Vout equals Vin minus dropout voltage (see Dropout vs. Load graph)

Note3: For more detailed information, please refer to trim table or calculation on page RPM-3

Note4: Required dropout voltage per 1A output current to be within accuracy (see Dropout vs. Load graph)

Note5: Measurements are made with a 22µF MLCC across output (low ESR)
