However, The regulator information is based on an older temporary pre-production board variant and does not reflect production board 750-2628-XXX boards. LDO3 supplies Low Latency Interface(LLI) hardware module which is a special hardware to communicate with Modem. However since uEVM is not setup by default for this communication, this should be disabled by default. Further, vdda_lli is supposed to be 1.5V and not 3V.
