Note:

4. a). Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and

functional operation of the device at these conditions is not implied. Exposure to absolute-maximum-rated conditions for extended period may affect

device reliability.

b). Ratings apply to ambient temperature at +25°C. The JEDEC STD.51 High-K board design used to derive this data was a 3 inch x 3 inch multilayer

board with 1oz. internal power and ground planes and 2oz. copper traces on the top and bottom of the board.

5. The AP7375 internal circuitry is not fully operation until VIN is at least the greater of 3V or (VOUT+VDROPOUT(MAX)).
