ZLDO1117中文资料single-ldos数据手册Diodes规格书

描述 Description

ZLDO1117 is a low dropout positive adjustable or fixed-mode regulator with 1A output current capability.  The ZLDO1117 has a 2% tolerance across the industrial temperature range and is guaranteed to have lower than 1.2V dropout at full load current making it ideal to provide well-regulated outputs of 1.2V to 

\t5.0V with input supply voltages up to 18V.  

\t 

\tThe ZLDO1117 is ideally suited to provide well-regulated supplies for low voltage IC applications such as high-speed bus termination and low current 3.3V logic supply across the whole industrial temperature range.

简介

ZLDO1117属于集成电路（IC）的线性+开关稳压器。由制造生产的ZLDO1117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。
