(1)
Minimum IN operating voltage is 2.7 V or VO(typ) + 1 V, whichever is greater. Maximum IN voltage 10 V.
(3)
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 (that is, TPS76830 input voltage must drop to 2.9 V
for the purpose of this test).
