NOTES:

4. Minimum IN operating voltage is 2.7 V or VO(typ) + 1 V, whichever is greater. Maximum IN voltage 10 V, minimum output current

10

µA, maximum output current 100 mA.

6. IN voltage equals VO(Typ) – 100mV; TPS76901 output voltage set to 3.3V nominal with external resistor divider. TPS76912,

TPS76915, TPS76918, TPS76925, and TPS76927 dropout voltage limited by input voltage range limitations.
