external PNP is provided. The external PNP configuration is offered to avoid excess on-chip power dissipation at high loads, and
large differential between BP and output settings. The input pin for the integrated PMOS option is shared with the base current
drive pin for the PNP option. The external PNP configuration must be committed as a hardwired board level implementation, while
the operating mode is selected through the VGEN3CONFIG bit after startup. The VGEN3 is not automatically enabled during the
power up sequence, allowing software to properly set the VGEN3CONFIG bit before the regulator is activated. The
recommended PNP device is the ON Semiconductor NSS12100XV6T1G, which is capable of handling up to 250 mW of
continuous dissipation at minimum footprint and 75 °C of ambient. For use cases where up to 500 mW of dissipation is required,
the recommended PNP device is the ON Semiconductor NSS12100UW3TCG. For stability reasons a small minimum ESR may
be required.

VGEN3 has an internal PMOS pass FET which will support loads up to 50 mA. For higher current capability, drive for an
A short circuit condition will shut down the VGEN3 regulator and generate an interrupt for SCPI.
Parameter
The max load given for VGEN1MODE = 0 and must take into account the capabilities of the external pass device and operating
conditions, to manage its power dissipation. Load capability is 3.0 mA for VGEN1MODE = 1.
The max load is given for as VGEN2MODE = 0, and must take into account the capabilities of the external pass device and operating
conditions to manage its power dissipation. Load capability is 3.0 mA for VGEN2MODE = 1.
