 Abstract
In this paper, we propose LDO regulator to operate using Pseude resistor instead of widely used Feedback resistor in conventional LDO regulator. Proposed Feedback network using Pseudo resistor has smaller area than the conventional feedback resistor and plays the role of an conventional LDO regulator. Thus, it has been proposed to compensate for the disadvantages of LDO regulator with noise. Although proposed LDO regulator compared with conventional LDO regulator has similar performance, this LDO regulator provide higher efficiency by reducing the overshoot and decreasing the area. This circuit was designed to using a Dongbu Hitek 0.18um CMOS process.
