CXLD64288一款低功耗、低噪声、低功耗、CMOS线性稳压器，工作电压范围为2.5V至5.5V。
CXLD64288是低电压、低功耗应用的最佳选择。低接地电流使这一部分对电池供电系统有吸引力。CXLD64288还提供超低的电压降，以延长便携式电子设备的电池寿命。需要安静电压源的系统，如射频应用，将受益于CXLD64288的超低输出噪声（30μVRMS）和高PSRR。外部噪声旁路电容器连接到设备的BP引脚可以进一步降低噪声水平。
其他功能包括在EN引脚上的110kΩ下拉电阻器、电流限制和热关机保护。
CXLD64288有绿色的UTDFN-1.6×1.6-6L和TDFN-2×2-6L两种包装。它在-40℃到+85℃的环境温度范围内工作

产品概述 返回TOP
The CXLD64288 is a low-power, low-noise, low-dropout, CMOS linear voltage regulator that operates from a 2.5V to 5.5V input voltage.
The CXLD64288 is the perfect choice for low voltage, low power applications. A low ground current makes this part attractive for battery operated power systems. The CXLD64288 also offers ultra low dropout voltage to prolong battery life in portable electronics. Systems requiring a quiet voltage source, such as RF applications, will benefit from the CXLD64288’s ultra low output noise (30μVRMS) and high PSRR. An external noise bypass capacitor connected to the device’s BP pin can further reduce the noise level.
Other features include a 110kΩ pull down resistor at EN pin, current limit and thermal shutdown protection.
The CXLD64288 is available in Green UTDFN-1.6×1.6-6L and TDFN-2×2-6L packages. It operates over an ambient temperature range of -40℃ to +85℃
