RTQ2532E 是一款高电流 (2A)、低噪声 (6.8μV<sub>RMS</sub>)、高精度（输入电压、负载与温度范围内 1%）、低压差线性稳压器 (LDO)，能够供出 2A 电流，且具备极低压差（最大 125mV）。此器件支持低至 1.1V 的单一输入供电电压，使其易于使用。<br />低噪声、高 PSRR 与高输出电流能力，使 RTQ2532E 非常适合为噪声敏感器件供电，例如模数转换器 (ADC)、数模转换器 (DAC) 与 RF 元件。凭借极高精度、远端检测，以及可降低浪涌电流的软启动能力，RTQ2532E 非常适合为 FPGA、DSP 与 ASIC 等数字负载供电。<br />外部启用控制与电源良好指示器功能使控制时序更容易。通过在 NR/SS 引脚增加外部旁路电容，可提升输出噪声抗扰度。此器件完整规格适用于 T<sub>J</sub> = -40°C 至 125°C 的温度范围，并提供 VQFN-20L 3.5x3.5 与 VQFN-20L 5x5 封装。
