1.5A双轨输入超低压差(75mV)LDO线性稳压芯片,兼容|对标|替代TPS74901 DFN10 3x3, QFN20 5x5封装






The NCP59748 is dual−rail very low dropout voltage regulator, capable of providing an output current in excess of 1.5 A with a dropout voltage of 60 mV typ. at full load current. The devices are stable with ceramic and any other type of output capacitor ≥ 2.2 uF. This series contains adjustable output voltage version with output voltage down to 0.8 V. Internal protection features consist of built-in thermal shutdown and output current limiting protection. User-programmable Soft-Start and Power-Good pins are available on both QFN and DFN versions.
The NCP59748 is offered in DFN10 3×3 and QFN20 5×5 packages.
