Hi Ti engineer，
Use TPS7A8300RGRR replace SGM2049XTRL20G/TR,But TPS7A8300RGRR did not output in specific tests.
Input 5.5V output 5V, start current 3A, duration 1.2ms, normal current 780mA, this power supply to the AD chip and operational amplifier power supply.
In the laboratory test, if the op amp there is not collected signal, TPS7A8300RGRR can be started when starting, if the op amp there is collected signal, TPS7A8300RGRR can not be output normally when starting.
Test LDO separately, 5V output, connected to electronic load, starting maximum current 1.35A
