目录7.相关产品 产品概述 返回TOP CXLD64196系列产品是实现了0.6μA超低消耗电流的电压调整器。此外,在输出电流为1μA(轻负载)时,也能得到稳定的电压,最适用于只需少量输出电流的应用目的。加上采用了0.75×0.95 mm的超小型封装USPN-4B02,对应了无稳定输出用电容(CL),可以大幅度减少实装面积。本IC由基准电压源,误差放大器,驱动晶体管,过电流保护电路,相位补偿电路等构成。尽管CL能对应陶瓷等低ESR电容,但由内部相位补偿即使没有CL也能实现稳定工作。由内部激光微调固定了输出电压,可以在1.1V~5.0V之间以0.1V的间隔选择产品。通过从CE端子输入L电平,可以使IC成待机状态,把消耗电流降低到0.1μA以下。此外,在待机状态时,用内部开关使充电在CL上的电荷放电,可以高速地返回到VSS电平。The CXLD64196 series is a highly accurate CMOS voltage regulator that achieves very low supply current operation of 0.6μA. Even output current is 1μA (when light load), the CXLD64196 can provide high accurate outputs, which is ideally suited for the applications to draw less output current. The usage of super small package USPN-4B02 (0.75 x 0.95mm) and the advantage of capacitor-less stable operation can contribute the board space saving outstandingly. The IC consists of a reference voltage source, an error amplifier, a driver transistor, over-current protection circuit, and a phase compensation circuit. The device is compatible with a low ESR ceramic output capacitor C Output voltage is fixed internally by laser trimming technology and can be selectable in 0.1V increments within the range of 1.1V to 5.0V. The CE function enables the device to be put into standby mode by inputting a low level signal to the CE pin thereby reducing current consumption to less than 0.1μA. In the standby mode, if a C L. Moreover, the device can provide stable output even without a CL output capacitor because of the excellent internal phase compensation. L output capacitor is used, the electric charge stored at CL can be discharged via the internal switch and as a result, the VOUT pin quickly returns to the VSS level. 产品特点 返回TOP
