1. Guaranteed by design and verified in lab characterisation.

2. External Schottky diode is mandatory for output voltages higher than 3V.

3. VOUT is forced to 3.6V in production test.

4. Internal pull-down resistor.

5. The POK parameters are tested with proprietary test modes.

Note: All limits are guaranteed. The parameters with min and max values are guaranteed with production tests or

SQC (Statistical Quality Control) methods.
