What is the input-output voltage difference?
Input-Output Voltage Difference VSAT = Input Voltage VIN – Output Voltage VOUT, or VIN = VOUT + VSAT In other words, the minimum input voltage that can still output the required VOUT (including the saturation voltage) should be calculated in order to minimize VSAT. The input-output voltage difference will vary depending on the output current. Therefore, the maximum current should be verified. Please refer to the ‘Output Current Iout-Input/Output Voltage Difference VSAT’ graph located in the technical notes for more information.
