目录7.相关产品 产品概述 返回TOP CXLD64168 CXLD64169系列是高精度,低噪声,采用CMOS工艺的正电压LDO调整器芯片。此系列调整器具有高纹波抑制和低输入输出压 差的特性。CXLD64168 CXLD64169系列芯片内部包括一个参考电压源,一个误差放大器,一个电流限制器,一个相位补偿电路和一个驱动三极管。CXLD64168 CXLD64169系列的输出电压范围是1.8V至6.0V,间隔为0.05V。CXLD64168 CXLD64169系列使用低ESR的陶瓷电容作负载电容,便可使输出稳定,并且具有良好的瞬态响应,即使负载变化也能保证电路稳定的工作。电流限制器的foldback电路为输出电流限制器和输出引脚提供短路保护。CXLD64168 CXLD64169系列具有的CE功能,可以关闭芯片的输出,因而极大地降低功耗。The CXLD64168 CXLD64169 series are highly precise, low noise, positive voltage LDO regulators manufactured using CMOS processes. The series achieves high ripple rejection and low dropout and consists of a standard voltage source, an error correction, current limiter and a phase compensation circuit plus a driver transistor. Output voltage is selectable in 0.05V steps within a range of 0.9V ~ 6.0V. The series is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the series. The current limiter's foldback circuit also operates as a short protect for the output current limiter and the output pin. The CE function enables the output to be turned off, resulting in greatly reduced power consumption. 产品特点 返回TOP
