目录7.相关产品 产品概述 返回TOP The CXSD62470 CXSD62471 is a high performance positive voltage regulator designed for use in applications requiring very low Input voltage and very low dropout voltage at up to 2 amps. It operates with a VIN as low as 1.4V and VPP voltage 5V with output voltage programmable as low as 0.8V. The CXSD62470 CXSD62471 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the CXSD62470 CXSD62471 has an enable pin to further reduce power dissipation while shutdown. The CXSD62470 CXSD62471 provides excellent regulation over variations in line, load and temperature. The CXSD62470 CXSD62471 provides a power OK signal to indicate if the voltage level of VO reaches 92% of its rating value. The GCXSD62470 CXSD62471is available in the power SOP-8 (FD) package. It is available with 2.5V internally preset outputs that are also adjustable using external resistors.产品特点 返回TOP „ Adjustable Output Low to 0.8V „ Input Voltage as Low as 1.4V and VPP Voltage 5V „ 300mV Dropout @ 2A, VO 2.5V „ Over Current and Over Temperature Protection „ Enable Pin „ Low Reverse Leakage (Output to Input ) „ Power SOP-8 (FD) Packages with Thermal Pad „ ±2% Output Voltage „ VO Power OK Signal „ 2.5V Options by Setting ADJ Pin Below 0.2V and Adjustable Externally Using Resistors „ VO Pull Low Resistance when Disable „ VO Soft Start When Enable 应用范围 返回TOP „ Motherboards „ Peripheral Cards „ Network Cards „ Set Top Boxes „ Notebook Computers 技术规格书（产品PDF) 返回TOP 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！ 产品封装图 返回TOP
