摘要：CXLD64216系列是一款超小型CMOS双LDO稳压器，具有300毫安的输出电流能力。该系列具有1%输出电压精度高、纹波抑制率高、漏失电压低的特点，采用超小型、高散热的LGA-6A01（1.2mm×1.2mm×h0.4mm）系列。该系列适用于高密度板的安装，通过控制EN-pin，每个调节器都可以独立关闭，处于待机状态。在这种状态下，输出电容器（CL）的电荷通过内部自动放电开关放电，结果输出电压迅速恢复到VSS水平。输出稳定电容器（CL）也与低ESR陶瓷电容器兼容。即使在频繁负载下，也能保持高水平的输出稳定波动，由于具有优异的瞬态响应性能。过电流保护电路和过热保护电路集成，当输出电流达到电流极限或结温达到温度极限时，这些电路开始工作。两个调节器完全隔离，以使负载波动期间的串扰最小化

The CXLD64216 series is an ultra small CMOS dual LDO regulator, with 300mA output current capability. The series features high accuracy of 1% output voltages, high ripple rejection and low dropout voltage.The series is available in LGA-6A01 (1.2mm × 1.2mm × h0.4mm) which features ultra small and high heat dissipation. The series is suited for high density board installation.Each regulator can be turned off independently to be in stand-by mode by controlling EN pin. In this state, the electric charge at the output capacitor (CL) is discharged via the internal auto-discharge switch, and as a result the VOUT voltage quickly returns to the VSS level.The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors.The high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance.Over current protection circuit and over heat protection circuit are integrated, these circuits start working when output current reaches current limit or junction temperature reaches temperature limit.The two regulators are completely isolated so that a cross talk during load fluctuations is minimized.ddR嘉泰姆
