CXLD6427CXLD6429系列是高精度、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，高纹波抑制比，低漏失和非常快的开启时间。每个调节器的输出电压通过激光微调独立设置。
CXLD6427 CXLD6429系列还与低ESR陶瓷完全兼容电容器，降低成本，提高输出稳定性。
即使在频繁的负载下也能保持这种高水平的输出稳定性波动，由于出色的瞬态响应性能和高PSRR在广泛的频率范围内实现。EN函数允许输出各调节器单独关闭，大大降低耗电量。

一,产品概述(General Description) 
The CXLD6427 CXLD6429 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 CXLD6427 CXLD6429 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 CXLD6427 series is available in the TSOT23-6L or
SOT23-6L packages(or upon request).
