描述 Description

The AZ1085C is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 3A of load current.

\t 

\tThe series features on-chip thermal shutdown. It also includes a bandgap reference and a current limiting circuit.

\t 

\tThe AZ1085C is available in 1.5V, 1.8V, 2.5V, 3.3V, 5.0V and adjustable versions. The fixed versions integrate the adjust resistors. The adjustable version can set the output voltage with two external resistors.

\t 

\tThe AZ1085C series is available in standard packages of TO263, TO263-2, TO252-2 (3), TO252-2 (4) and TO252-2 (5).

简介

AZ1085C属于集成电路（IC）的线性+开关稳压器。由制造生产的AZ1085C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。
