AP7173中文资料single-ldos数据手册Diodes规格书

描述 Description

The AP7173 is a 1.5A low-dropout (LDO) linear regulator that features a user-programmable soft-start, an enable input and a power-good output. The soft-start reduces inrush current of the load capacitors and minimizes stress on the input power source during start-up. The enable input and power-good output allow users to configure power management solutions that can meet the sequencing requirements of FPGAs, DSPs, and other applications with different start-up and power-down requirements. The AP7173 is stable with any type of output capacitor of 2.2μF or more. A precision reference and feedback control deliver 2% accuracy over load, line, and operating temperature ranges. The AP7173 is available in both DFN3030-10 and SO-8EP packages.

简介

AP7173属于集成电路（IC）的线性+开关稳压器。由制造生产的AP7173稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
