Figure 6. Reference Management
The output regulated voltage accuracy can be extracted from the following relationships (worst case con-
dition):
(worst case with internal reference)
(worst case with external reference)
where VOS_RA and VOS_EA are the offsets related to the Error Amplifier and the Remote Amplifier respec-
tively and KOS = 1+1/RA_Gain reflects the impact of the Remote Amplifier Gain (RA_Gain) on the regula-
tion (see relevant section).
A statistical analysis could consider applying the root-sum-square (RSS) method to calculate the precision
since all the variables are statistically independent as follow:
(with internal reference)
(with external reference)
