双低输出稳压器一路输出为3.3V 0.5A，另一路输出2.5V 0.3A低压降瞬态响应CXLD64145电流限制

CXLD64145是一个双低输出稳压器，输出1为3.3V/0.5A，输出2为2.5V/0.3A。为了获得较低的压降和较快的瞬态响应，这对低压应用至关重要，对APL5221进行了优化。输出端1的压降保证在0.5A时为1.25V，输出端2的压降保证在0.3A时为1.2V。电流限制被修剪以确保指定的输出电流和控制短路电流。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 CXLD64145 is a dual low dropout regulator with output 1 with 3.3V/0.5A and output2 with 2.5V/0.3A output capability. In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications,  has been optimized. The dropout voltages are guaranteed at 1.25V at 0.5A for output1 and 1.2V at 0.3A for output 2. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. The CXLD64145 regulator comes in a SOP-8 package.
