Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its nominal value. 7. Quiescent current is defined here is the difference in current between the input and the output. 8. Short circuit current is measured with VOUT pulled to GND. 9. This specification is guaranteed by design. 10. To make sure lowest environment noise minimizes the influence on noise measurement. 11. AP7343Q has two options for output, built-in discharge and non-discharge. 12. Potential multiple grades based on following output voltage accuracy.
