Why PP3V3_AON this line is comes and goes back?

See other element measurements: U8100 VIN_LDOS: PP3V8_AON_MPMU_ISNS --> 3.8 VDC VLDOS: PP3V3_S2 - missing power PP1V8_S2SW_CLVR_VDDC1_LDO - missing power PP3V3_AON - this power line is fluctuating on Siglent Multimeter. So it shows 3.3 goes to 2.6 and loops PP1V8_AON -- 1.8 VDC PP1V2_AON --...

PPVIN_P3V8AON_ISNS --> missing power

U7700 PP1V2_S2 --> missing power PP3V3_S2 --> missing power PP1V8_S2 --> missing power PP5V_S2_MAIN --> missing PP3V3_AON --> this power line is fluctuating on Siglent Multimeter. So it shows 3.3 goes to 2.6 and goes to zero and loops.
