Analog Devices Inc. ADM7151 RF线性稳压器

Analog Devices ADM7151是一款低压差线性稳压器，采用4.5 V至16V电源供电，最大输出电流为800mA。这些器件采用先进的专有架构，提供高电源抑制(>90dB从 1kHz到1MHz)、超低噪声特性，利用一个10μF陶瓷输出电容，便可实现出色的线路与负载瞬态响应性能。使用两个电阻，输出电压可设为1.5V至5.1V范围内的任意电压值。ADM7151稳压器输出噪声为1.0μV rms（100Hz至100KHz），10KHz以上时的噪声频谱密度为1.7nV/√Hz。ADM7151不仅非常紧凑，而且还具有出色的散热性能，适合要求最大800mA输出电流的薄型、小尺寸应用。

The ADM7151 regulator output noise is 1.0μV rms from 100Hz to 100kHz, and the noise spectral density is 1.7nV/√Hz from 10kHz to 1MHz. The ADM7151 is a very compact solution, and also provides excellent thermal performance for applications requiring up to 800 mA of output current in a small, low profile footprint.
