Cxld6433 series is a high ripple rejection, low voltage difference, high precision output voltage, low consumption current positive voltage voltage regulator developed by CMOS technology
Cxld6433 series is a high ripple rejection, low voltage difference, high precision output voltage, low consumption current positive voltage voltage regulator developed by CMOS technology. Because of the built-in low-pass resistance transistor, the differential pressure is low and the output current can be larger. In order to make the load current not exceed the current capacity of the output transistor, the overload current protection circuit, temperature protection circuit and short circuit protection circuit are built in. In addition, due to the small package of sot-89-3, it can be installed with high density.

Product introduction
| 一,产品概述(General Description) CXLD6433系列是使用CMOS技术开发的高纹波抑制，低压差， 高精度输出电压，低消耗电流正电压型电压稳压器。由于内置有低 通态电阻晶体管，因而压差低，能够获得较大的输出电流。为了使 负载电流不超过输出晶体管的电流容量，内置了过载电流保护电路、 温度保护电路、短路保护电路。此外，因采用SOT-89-3小型封装， 故可高密度安装。 二.产品特点(Features) 可选择输出电压 ：可以在1.5～5.5V的范围内选择,并以0.1 V为单位进级 输出电压精度高： 精度可达±2.0%(客户要求) 输入输出压差低 ：典型值150 mV (输出为3.0V的产品, IOUT=100mA时) 消耗电流少 ：工作时典型值60μA、最大值120μA 输出电流大 ：可输出500mA(VIN≥VOUT+1V) 内置电源开/关控制电路 ：能够延长电池的使用寿命 高纹波抑制率 ：典型值60dB (1.0 kHz 时) 采用小型封装 三,应用范围 (Applications) DVD 驱动器，CD-ROM 驱动器稳压电源 使用电池供电的设备的稳压电源 通信设备的稳压电源 笔记本电脑用的稳压电源 四.下载产品资料PDF文档 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 五,产品封装图 (Package)  六.电路原理图
