7.3.3 Drop-Out Voltage

The drop-out voltage of a voltage regulator is the difference between the input voltage and the output voltage that is required to maintain regulation. Figure 16 and Figure 17 show typical drop-out voltage graphs for TPSM84205 at ambient temperatures of 25°C and 85°C. Figure 18 and Figure 19 show typical drop-out voltage graphs for TPSM84212 at ambient temperatures of 25°C and 85°C.
