Abstract: This study presents the design criteria of Low Drop Out (LDO) regulator using a high precision Band Gap Reference (BGR) which make the system independent of PVT variations. The inspiration behind the study of LDO regulators is driven by the increasing demand for higher performance power supply circuits. The BGR provides a reference voltage of 0.9 V, that can be vary according to the requirements. The designed LDO will provide an output voltage of 1.8 V with ±3% variation across the PVT variations. The study further illustrates the analysis and the results relevant to the LDOs and BGR using 55 nm CMOS technology.
