NOTES:
2. Minimum IN operating voltage is 2.5 V or VO(typ) + 1 V, whichever is greater. Maximum IN voltage 7 V.
3. If VO = 1.5 V then Vimax = 7 V, Vimin = 2.5 V:
4. IN voltage equals VO(Typ) – 100 mV; TPS7430 and TPS7433 dropout limited by input voltage range limitations (i.e., TPS7430 input
voltage needs to drop to 2.9 V for purpose of this test).
