Analog Devices Inc. ADP1740/ADP1741 CMOS线性稳压器
Analog Devices ADP1740/ADP1741 CMOS线性稳压器的工作电压为1.6V至3.6V，输出电流高达2A。 这些低VIN/VOUT稳压器很适合用于调节从2.5V降至1.8V I/O电压轨工作的纳米FPGA几何结构。 ADP1740/ADP174稳压器也是一款为低至0.75V的内核电压供电的理想器件。该稳压器采用先进的专有架构，噪声低、电源抑制比高。 该器件还可通过小型4.7μF陶瓷输出电容器实现出色的线路和负载瞬态响应。 此外，ADP1740/ADP1741稳压器还可提供可调输出电压选项。 这些可调输出电压范围为0.75V至3.3V。这些稳压器采用4mmx4mm LFCSP封装，可为需要高达2A输出电流的薄型封装应用提供出色的热性能。
These devices also achieve an excellent line and load transient response with a small 4.7µF ceramic output capacitor. In addition, the ADP1740/ADP1741 Regulators offer adjustable output voltage options. These adjustable output voltages range from 0.75V to 3.3V. Available in a 4mm×4mm LFCSP package, the Regulators provide excellent thermal performance for applications with a low-profile footprint that require up to 2A output current.
