目录7.相关产品 产品概述 返回TOP CXLD64195系列是输出电压范围为1.2V~5.0V(0.05V间隔),最大输出电流500mA,即使不使用稳定输出的电容(CL)也能实现稳定工作的CMOS LDO电压调整器。因为不需使用稳定输出的电容(CL)也能实现稳定工作,能以极小的尺寸构成包括外置元件的电源电路。保护电路中内置了反馈电路(限定输出电流及输出引脚的短路保护)和过热保护电路。CXLD64195P是有3个引脚的电压调整器。CXLD64195D具有CE引脚,能输入低电平使IC处于待机状态。此外,在使用稳定输出的电容(CL)时,能由内部开关使CL的充电电荷放电。此放电功能可使VOUT引脚高速地返回到VSS电平。The CXLD64195 series is a 500mA high speed CMOS LDO regulator that can provide stable output voltages even without a load capacitor CL. The devices are available in fixed output voltage from 1.2V to 5.0V in 0.05V increments The CL capacitor-less is possible because phase compensation is carried out internally unlike other LDOs where it is done externally. It results in saving board design space. The current limit fold-back circuit and thermal shutdown circuit work as protection circuit. The CXLD64195P is a 3-Terminal regulator and the CXLD64195D has a chip enable function, which enables the entire circuit to be turned off by a low level input signal to the CE pin. When a CL capacitor is used, the IC can discharge the electric charge stored at the output capacitor through the internal switch while in standby state, and as a result the VOUT quickly returns to the VSS level. 产品特点 返回TOP
