Other Parts Discussed in Thread: LMR36015
The datasheet states that the EN voltage "must not exceed the voltage on the VIN pin by more than 0.3V".
Would like to confirm this is under all conditions and is not just applicable to maximum ratings. Take a 12V system with separate "battery" and "ignition" or "wake" signals. The LMR36015 cannot handle failure modes where the supply supporting the VIN pin is interrupted but the supply connected to the EN pin is still present. I.e. VIN is floating but EN is at 12V. Other external support circuitry is required for this.
Take Care,
Steve
