  • Product Details:

    ADM7172是一款CMOS、低压差(LDO)Linear regulator，采用2.3 V至6.5 V电源供电，最大输出电流为2 A。 这款高输出电流LDO适用于调节6 V至1.2 V供电的高性能模拟和混合信号电路。 该器件采用先进的专有架构，提供高电源抑制、低噪声特性，仅需一个4.7 μF小型陶瓷输出电容，便可实现出色的线路与负载瞬态响应性能。 对于1 mA至1.5 A负载阶跃而言，负载瞬态响应通常为1.5 μs。

    ADM7172 offers 17 fixed output voltage options. The following voltage versions are available in stock at 1.3 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V, 4.2 V, and 5.0 V. The following voltage versions are also available on special request: 1.5 V, 1.85 V, 2.0 V, 2.2 V, 2.7 V, 2.75 V, 2.8 V, 2.85 V, 3.8 V and 4.6 V. An adjustable model is also available that regulates the output voltage range from 1.2 V to VIN − VDO via an external feedback divider.

    The start-up time is adjusted by the soft-start pin, which controls the inrush current. The typical start-up time with a 1 nF soft-start capacitor is 1.0 ms.

    ADM7172 regulator has an output noise of 5 μV rms and is not affected by the output voltage. ADM7172 available in an 8-pin, 3 mm x 3 mm LFCSP package, it is extremely compact and offers excellent thermal dissipation for thin, small form factor applications requiring a maximum output current of 2 A.
