CXLD64146是一个双低输出稳压器，输出1为3.3V/0.5A，输出2为2.5V/0.5A。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CXLD64146进行了优化。500毫安负载时，VOUT1的典型电压降为550毫伏，500毫安负载时，VOUT2的典型电压降为630毫伏。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。

产品概述 返回TOP
The CXLD64146 is a dual low dropout regulator with output 1 with 3.3V/0.5A and output2 with 2.5V/0.5A output capability. In order to obtain lower dropout voltage and faster transient response, which is critical for low voltage applications, the CXLD64146 has been optimized. VOUT1 typical dropout voltage is 550mV at 500mA loading and VOUT2 typical dropout voltage is 630mV at 500mA loading. 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 CXLD64146 regulator comes in a SOP-8 and SOP-8P packages
