Abstract
This paper proposes the Low-Dropout regulator with two output. Each of the two output has feedback, and shared feedback loop. PMOS is added to solve the problem the occur when sharing the feedback loop. Thus eased the Load Transient Response. Also Using one of the bias citcuit and one of the pass transistor, Area is reduce by half compared to Existing Area that used to obtain output of two output.
