Retrieved The output voltage is less susceptible to variation of input voltage, resulting in a clean and stable voltage which is used the operating voltage of internal circuits in a mixed-mode signal integrated circuit chip. This proposed circuit is design and implemented using the TSMC 0. Like other electronic devices, LDOs are affected by thermal noisebipolar shot noiseand flicker noise. This is especially useful when a system is using switcherswhich introduce a ripple in the output voltage occurring at the switching frequency. For high voltages under very low In-Out difference there will be significant power loss in the control circuit.

      The advantages of a low dropout voltage regulator over other DC to DC regulators include the absence of switching noise as no switching takes placesmaller device size as neither large inductors nor transformers are neededand greater design simplicity usually consists of a reference, an amplifier, and a pass element.
