This paper is a review paper on Low Dropout (LDO) Voltage Regulator. Various techniques that have been proposed to improve performance parameters of LDO are studied and their performance is compared with the proposed Low Dropout (LDO) voltage regulator using Bulk Modulation Technique. The proposed LDO regulator is able to delivers up to 5 mA of load current while providing 1 V (~1.5% load regulation) drawing 99.0 µA from a 1.2 V supply. It has been observed that the proposed circuit offers better stability as well as 75% improvement in the load current delivery and recovery time of 0.16 µs for no-load to full-load transition. The proposed LDO is implemented in a standard 0.13-μm CMOS process. |
