LP2951ACMM-3.3 developed by Texas Instruments is a type of adjustable micropower voltage regulator specifically designed for battery-powered systems. It can be used for battery-powered systems to ensure ultra-low noise, extremely low dropout voltage, and low quiescent current. The battery life can be prolonged since the quiescent current increases only slightly in dropout. It can be used as a low-power voltage reference based on its careful design including a tight initial tolerance, extremely good load and line regulation, and a very low output voltage temperature
