AZ1117C中文资料single-ldos数据手册Diodes规格书

描述 Description

The AZ1117C is a low dropout three-terminal regulator.
\t
\t\tThe AZ1117C has been optimized for low voltage where transient response and minimum input voltage are critical. It provides current limit and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within ±1%. On-chip thermal shutdown provides protection against a combination of high current and ambient temperature that would create excessive junction temperature.
\t
\t\tThe AZ1117C is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V fixed output voltage versions and ADJ output voltage version. The fixed versions integrate the adjust resistors. It is also available in an adjustable version which can set the output voltage with two external resistors.
\t
\t\tThe AZ1117C is available in the industry-standard TO2522 (3), TO2522 (4), and TO2522 (5), SOT89-3L and SOT223 power packages.

简介

AZ1117C属于集成电路（IC）的线性+开关稳压器。由制造生产的AZ1117C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。
