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.
