AP7217中文资料single-ldos数据手册Diodes规格书

描述 Description

The AP7217 low-dropout linear regulator operates from a 3.3V to 5.5V supply and delivers a guaranteed 500mA (min) continuous load current. The high-accuracy output voltage is preset to an internally trimmed voltage. An active-low open-drain reset output remains asserted for at least 20ms (TYP) after output voltage reaches VDF. The space-saving SO-8 package is suitable for “pocket” and hand-held applications.

简介

AP7217属于集成电路（IC）的线性+开关稳压器。由制造生产的AP7217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。
