Dear,
I know there is the accuracy equation §10 in the document "Technical Review of Low Dropout Voltage Regulator Operation and Performance" SLVA072.
But I need to have the output voltage equation in regard with the line regulation and the load regulation.
The typical output equation is :
Vout = Vfb * (1 + R2/R1) + Ifb * R2.
How shall I integrate the line and load regulation to this equation?
Proposal 1 : Vout = Vfb * (1 + R2/R1) + Ifb * R2 + Vl + Vld
Proposal 2 : Vout = (Vfb + Vl + Vld) * (1 + R2/R1) + Ifb * R2
Vl : Line regulation
Vld : Load regulation
Best regards
