ABSTRACT

This paper presents the design of Low Drop-Out (LDO) voltage regulator has fast transient response and which exploits a few current else low quiescent current in the operational amplifier PMOS type. We use band-gap reference for eliminate the temperature dependence. The proposed LDO voltage regulator implemented in 0.18-µm CMOS technology, we use Folded cascode CMOS amplifiers high performance in the stability , provide fast transient response which explains a fast settling, the LDO itself should provide in the output regulator voltages at ∆t equal 2ps with transient variation of the voltage less than 170mV. High accuracy in the DC response terms, the simulation results show that the accuracy of the output regulator voltages is 1.54±0.009V, and power consumption of 1.51 mW.
