Notes:

7. Short-circuit current is measured with VOUT pulled to GND.

8. Quiescent current defined as the difference in current between the input and the output.

9. Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its nominal value.

10. AP7354 is available with two options: built-in discharge (AP7354D) and non-discharge (AP7354).

11. Test condition: Device mounted on 1" × 1" FR-4 MRP substrate PCB, 2oz copper, with minimum recommended pad layout.
