Abstract
In this paper Low Drop-Out (LDO) regulator that improved load regulation characteristics due to the feedback detection structure. The proposed feedback sensing circuit is added between the output of the LDO's internal error amplifier and the input of the pass transistor to improve the regulation of the delta value coming into the output. It has a voltage value with improved load regulation characteristics than existing LDO regulator. The proposed LDO structure was analyzed in Samsung 0.13um process using Cadence's Virtuoso, Spectre simulator.
