Product Overview
产品说明
NCP59749 is 3 A ultra-low dropout voltage regulator, capable of providing an output current in excess of 3 A with a dropout voltage of 120 mV typ. at full load current. Output voltage is adjustable down to 0.8 V. Internal protection features consist of thermal shutdown and output current limiting protection. Additional features include user-programmable Soft-Start and Power-Good. NCP59749 is available in 5x5 QFN20 package.
