Texas Instruments TPS7A92低噪声低压差稳压器
Texas Instruments TPS7A92低噪声低压差稳压器器件是一款低噪声 (4.8µVRMS) 低压差 (LDO) 稳压器,可在压差仅为180mV时提供2A拉电流。TPS7A92的输出可通过外部电阻在0.8V至5.2V范围内进行调节。TPS7A92的宽输入电压范围支持其在1.4V至6.5V范围内的电压下工作。1%输出电压精度(整个线路、负载和温度范围内)以及软启动功能可减少浪涌电流,因此,TPS7A92非常适合为敏感类模拟低压器件供电。这些器件包括压控振荡器 (VCO)、模数转换器 (ADC)、数模转换器 (DAC)、高端处理器和现场可编程门阵列 (FPGA)。TPS7A92设计用于为噪声敏感型元器件供电,例如高速通信、视频、医疗或测试与测量应用的元器件。特性
