Design of Ultra-low Power Consumption Low-dropout Regulator

Journal of Physics: Conference Series, 2020
Abstract This paper designs a type of ultra-low power consumption LDO with the CSMC 0.5μm technology, which can output the 1.5V voltage. In this LDO, the error amplifier is structed with two-stage operational amplifiers. The input of first stage uses PMOS differential pairs that can decrease the noises and the second stage uses the ...
