Note: The DCDC load support increases with VDDS supply voltage up to a specific supply threshold. Beyond this threshold the load support typically drops before increasing again until the next threshold. For high TX output power settings, the load on VDDR can exceed the DCDC load support and the extra load is supplied by internal GLDO. This manifests as multiple slight peaks on the TX current curve as a function of increasing VDDS supply voltage.
Table 7-1 shows typical TX current and output power for different output power settings.
