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). 3 Submit Documentation Feedback |
