(1) When VOUT ≤ 3.5 V, VIN ≥ (VOUT + 0.3 V) or 1.425 V, whichever is greater; when VOUT > 3.5 V, VIN ≥ (VOUT + 0.7 V).
(2) VOUT(TARGET) is the calculated target VOUT value from the output voltage setting pins: 50mV, 100mV, 200mV, 400mV, 800mV, and 1.6V in fixed configuration, or the expected VOUT value set by external feedback resistors in adjustable configuration.
(3) R2 is the bottom-side of the feedback resistor between the FB pin and GND. See the Traditional Adjustable Configuration section for details.
(4) This 50-Ω load is disconnected when the test conditions specify an IOUT value.
(5) When the TPS7A7300 is connected to external feedback resistors at the FB pin, external resistor tolerances are not included.
(6) The TPS7A7300 is not tested at VOUT = 0.9 V, 2.7 V ≤ VIN ≤ 6.5 V, and 500 mA ≤ IOUT ≤ 3 A because the power dissipation is higher than the maximum rating of the package. Also, this accuracy specification does not apply on any application condition that exceeds the power dissipation limit of the package.
(7) V(DO) is not defined for output voltage settings less than 1.2 V.
(8) CFF is the capacitor between FB pin and OUT.
