(1) The TPS73801 regulators are tested and specified under pulse load conditions such that T_J is approximately equal to T_A. The TPS73801 is fully tested at T_A = 25°C. Performance at –40°C and 125°C is specified by design, characterization, and correlation with statistical process controls.

(2) The TPS73801 is tested and specified for these conditions with the FB pin connected to the OUT pin.

(3) Dropout voltages are limited by the minimum input voltage specification under some output voltage and load conditions.

(4) Operating conditions are limited by maximum junction temperature. The regulated output voltage specification does not apply for all possible combinations of input voltage and output current. When operating at maximum input voltage, the output current range must be limited. When operating at maximum output current, the input voltage range must be limited.

(5) To satisfy requirements for minimum input voltage, the TPS73801 is tested and specified for these conditions with an external resistor divider (two 4.12-kΩ resistors) for an output voltage of 2.4 V. The external resistor divider adds a 300-μA DC load on the output.

(6) Dropout voltage is the minimum input to output voltage differential needed to maintain regulation at a specified output current. In dropout, the output voltage is equal to: V_IN – V_DROPOUT.

(7) GND pin current is tested with V_IN = (V_OUT(NOMINAL) + 1 V) and a current source load. The GND pin current decreases at higher input voltages.

(8) FB pin bias current flows into the FB pin.

(9) Reverse output current is tested with the IN pin grounded and the OUT pin forced to the rated output voltage. This current flows into the OUT pin and out the GND pin.

(10) Typical values represent the likely parametric nominal values determined at the time of characterization. Typical values depend on the application and configuration and can vary over time. Typical values are not specified on production material.
