Notes:

3. Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account separately.

4. During output over-voltage protection, the output draws approximately 60µA current.

5. Since the output turn-on slew rate is dependent on input supply slew rate, this limit is only applicable for input supply slew rate between 5V/0.2ms to

5V/1ms.

6. Device mounted on FR-4 substrate PCB, 2oz copper, with minimum recommended pad layout.

7. Applicable for output voltage slew rate

≤ 5V/30μs.
