NOTES:

2. To calculate the minimum input voltage for your maximum output current, use the following formula:

VI(min) = VO(max) + VDO (max load)

3. Continuous output current is limited by internal protection circuitry, but it is not recommended that the device operate under

conditions beyond those specified in this table for extended periods of time.

4. The minimum IN operating voltage is 1.8 V or VO (typ) + 1 V, whichever is greater. The maximum IN voltage is 5.5 V. There is no

minimum output current requirement and the maximum output current is 10 mA.

5. IN voltage equals VO(typ) −100 mV; The TPS79730 input voltage is set to 2.9 V and the TPS79733 input voltage is set to 3.2 V. The

TPS79718 dropout voltage is limited by input voltage range limitations.
