目录7.相关产品 产品概述 返回TOP CXLD64197系列产品是在实现了消耗电流达到了非常低的5.5μA的同时,与既往的高速LDO具有相同等级的负载瞬态响应特性;高精度,低噪声,低压差的CMOS LDO电压调整器。本IC由基准电压源,误差放大器,驱动器晶体管,电流限定电路,过热保护电路,相位补偿电路等构成。作为CE功能,在CE引脚输入低(L)电平电压能停止电压调整器的输出成为待机状态。此外,具有CL放电功能的产品,能用VOUT引脚与VSS引脚之间的内部开关,将稳定输出用的电容(CL)的充电电荷放电,使VOUT引脚高速地返回到VSS电平。内置了过电流保护电路和过热保护电路,当输出电流达到了限定电路,或结温度达到了检测温度时,保护电路开始工作。Even the CXLD64197 series is a low power consumption such as 5.5μA, the IC is a high speed CMOS LDO regulator that features high accurate, low noise, high ripple rejection, and low dropout. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a phase compensation circuit and a thermal shutdown circuit. The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the series enables the electric charge at the output capacitor CL to be discharged via the internal switch, and as a result the VOUT pin quickly returns to the VSS level. The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate when the output current reaches current limit level or the junction temperature reaches temperature detection level. 产品特点 返回TOP
