目录7.相关产品 产品概述 返回TOP CXLD64173系列是采用CMOS生产工艺的高精度,低噪声,大电流,低输入输出电压差的正电压调整器。此系列芯片内置有参考电压源,误差放大器,电流限制器,相位补偿器和一个驱动晶体管。由于内置了一个低导通电阻的驱动晶体管,即使在输入输出电压差很小时也可保证电池的正常使用,从而延长了电池的使用寿命。此系列调整器可使用低ESR的陶瓷电容便可使输出稳定。输出电压是从0.8V到5.0V,间隔为0.05V。电流限制器的反馈回路可作为输出电流限制器并保护输出引脚。通过CE功能可使芯片处于待机状态,此时功耗被极大地降低。The CXLD64173 series are precise, low noise, high current, positive voltage low dropout regulators. They are fabricated using Torex’s CMOS process. The series features a voltage reference, an error amplifier, a current limiter, and a phase compensation circuit plus a driver transistor. With a low ON resistance driver transistor built into, batteries can be used until input-output voltage differential is minimal and can accordingly be used for a longer time. The series is also compatible with low ESR ceramic capacitors which give added output stability. The output voltage of the LDO is selectable in 0.05V increments within the range of 0.80V to 5.00V. The current limiter's foldback circuit also operates as the output current limiter and the output pin protection. The IC's internal regulator circuit can be placed in stand-by mode via the CE function. In the stand-by mode, power consumption is greatly reduced. 产品特点 返回TOP
