4. IN voltage equals VO(Typ) – 100 mV; TPS76501 output voltage set to 3.3 V nominal with external resistor divider. TPS76515,

TPS76518, TPS76525, and TPS76527 dropout voltage limited by input voltage range limitations (i.e., TPS76530 input voltage

needs to drop to 2.9 V for purpose of this test).
