(2) The dropout voltage is the input/output differential at which the circuit ceases to regulate against further reduction in input voltage. It is measured when the output voltage has dropped 100 mV from the nominal value obtained at Vin=Vout+1.5V. 2 IL233-x Block Diagram Application Information FIGURE 1.
