The ADM7150ARDZ-3.3-R7 is a 800mA Ultra-Low Noise (ULN) LDO voltage regulator designed and manufactured by Analog Devices. It offers a wide range of output voltages from 2.5 to 3.3V when used with a fixed drop out voltage, as well as an adjustable output voltage with a variable drop out voltage. The device also features an improved noise performance which makes it suitable for powering high precision analog circuits. It also includes under voltage lockout for improved system reliability and a very low no-load quiescent current of 100uA.
