双通道3.3V/500mA和1.8V/300mA线性稳压器CXLD64147内置限流保护快速瞬态响应

CXLD64147是一个双低压差稳压器，输出1为3.3V/0.5A，输出2为1.8V/0.3A输出能力。为了获得较低的压降和更快的瞬态响应，这对低压应用至关重要，对CXLD64147进行了优化。输出1的压降保证为0.6V（0.5A），输出2的压降保证为0.9V（0.3A）。电流限制被调整以确保指定的输出电流和受控的短路电流。片上热限制提供了保护，防止过载的任何组合，将产生过高的结温。

The CXLD64147 is a dual low dropout regulator with output1 with 3.3V/0.5A and output2 with 1.8V/0.3A output capability. In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications, the CXLD64147 has been optimized. The dropout voltages are guaranteed at 0.6V at 0.5A for output1 and 0.9V at 0.3A for output 2. Current limit is trimmed to ensure specified output current and controlled shortcircuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. The CXLD64147 regulator comes in a SOP-8 and SOP-8P packages.
