1. VSREG at device pin after reverse battery protection, while application is supplied with 6V. Operating condition has to be
adapted, if higher voltage drop occur in the application.
2. Put into the datasheet, if it is an internal voltage. If it is an external pin, it should be supplied externally.
3. Measurement equipment input load <20 pF, >1 MΩ, guaranteed by E.025, E.026, E.029, E.030, E.053, E.054
measurements.
