产品概览
The LT1761ES5-SD#TRPBF from Analog Devices (Linear Technology) is a 100mA low-noise LDO linear regulator with shutdown in a SOT-23-5 package. The SD suffix denotes the adjustable output version, featuring 20uVRms output noise, 300mV dropout at 100mA, and 20uA quiescent current, making it ideal for noise-sensitive battery-powered applications.
