NOTE 4: IN voltage equals VO(typ) – 100 mV; TPS76801 output voltage set to 3.3 V nominal with external resistor divider. TPS76815, TPS76818,

TPS76825, and TPS76827 dropout voltage limited by input voltage range limitations (i.e., TPS76830 input voltage needs to drop to

2.9 V for purpose of this test).
