CXLD6426高精度双低噪声CMOS LDO电压调节器低ESR陶瓷电容器高的PSRR频率瞬态响应

CXLD6426系列具有高精度、双低噪声、CMOS LDO电压调节器。该系列的性能特点包括低输出噪声、高纹波拒绝率，低辍学和非常快的开机时间。每个调节器的输出电压通过激光微调独立设置。
CXLD6426系列还与低ESR陶瓷电容器完全兼容，降低成本，提高产量稳定性。这种高水平的输出稳定性即使在频繁的负载波动中也能保持，由于具有优异的瞬态响应性能和较高的PSRR
频率范围很广。EN功能允许每个调节器的输出单独关闭，大大降低了功耗。

一,产品概述(General Description)      

   The CXLD6426 series are highly accurate, Dual low noise, CMOS LDO voltage
regulators.Performance features of the series include low output noise, high ripple
rejection ratio, low dropout and very fast turn-on times.
    The output voltage for each regulator is set independently by laser trimming.
The CXLD6426 series is also fully compatible with low ESR ceramic capacitors,
reducing cost and improving output stability.
This high level of output stability is maintained even during frequent load fluctuations,
due to the excellent transient response performance and high PSRR achieved across
a broad range of frequencies. The EN function allows the output of each regulator
to be turned off independently, resulting in greatly reduced power consumption. The 

CXLD6426 series is available in the TSOT23-6L or SOT23-6L packages(or
upon request).
