目录7.相关产品 产品概述 返回TOP CXLD64164系列是一款输出电流可达到1A,低压差,正电压调整器芯片。它有三种固定输出电压型号(VOUT型),其输出电压值分别为:1.8V, 2.5V, 3.3V和5.0V(CXLD64164P),和一种输出电压通过外部电阻可调的型号(CXLD64164K)。其中输出为5.0V的VOUT型与输出为1.8V, 2.5V和3.3V的VOUT型有所不同(具体情况请参考电气特性)。当输出电流为1A时输出电压相对输入电压会产生1.2V的电压降(TYP.)。当工作电流达到芯片的最大限流或温度达到最大耐热值时,芯片内置的过流或热保护电路会自动起保护作用。CXLD64164系列在允许的温度变化范围内,为了保证电路工作的稳定,请在芯片的输入输出端分别加一个10uF的钽电容。CXLD64164系列采用SOT-223封装。The CXLD64164 series is 1A Bi-polar transistor LDO voltage regulator. Output voltage of the CXLD64164P series is fixed to 1.8V, 2.5V, 3.3V, and 5.0V. The CXLD64164K series output voltage is adjustable by the external resistors. Please refer to the absolute maximum ratings for the difference between the rated input voltage of the CXLD64164P50 (VOUT=5.0V) and CXLD64164P18, 25, 31, K12B. With the dropout voltage 1.2V (TYP.), output current can be generated up to 1A. The built-in overcurrent circuit and thermal protection circuit start to operate when either one of output put current reaches the current limit level or junction temperature reaches the temperature limit. The CXLD64164 series provide stable line and load regulation by using an input capacitor and an output capacitor (10μF, tantalum). Package is available in SOT-223. 产品特点 返回TOP
