Design of stable 3.3V to 1.8 V,100 mA Low Drop out voltage Regulator Using 180nm Technology

This paper presents the design of a specific low dropout (LDO) voltage regulator, aiming to ensure a stable output voltage of 1.8 V. This circuit operates within an input voltage range of 3.3 V to 2.2 V and provides a maximum current output of 100 mA. LDOs play a crucial role in electronic devices by regulating voltage and delivering stable voltage to delicate components. The described LDO in this study emphasizes a high current output capability while minimizing output voltage fluctuations. Its versatility makes it applicable in diverse scenarios, including battery-powered devices, sensors, and portable electronics that demand strict adherence to the stable output voltage [11] – [20].
