产品概述 返回TOP
The CXLD64149 is a dual channel low dropout linear regulator, which operates from 2.5V to 5.5V input voltage and delivers up to 300mA output current at each channel. Typical dropout voltage is only 270mV at 300mA. The CXLD64149 with low quiescent current, high PSRR, and low noise is ideal for battery powered system appliances. Other features include logic-controlled shutdown mode, over-temperature protection, short-circuit current-limit, and current-limit protection to ensure specified output current. The CXLD64149 is available in SOT-23-6, TSOT-23-6A, and TDFN1.6x1.6-6 packages.
