Note
For a complete description of the electrical characteristics of the different output power rails (PMIC regulators), see the NXP PF8x00 datasheet.
1
The maximum output current involves both external and internal circuitry. For those regulators that are used internally in the SOM, the current
available outside it will be lower.
2
Turn-on time for this regulator is specified for VSW7 = 1.8 V. In the ConnectCore 8X this regulator is configured to work at 3.3V, so a higher turn-on time
may be observed.
