LM1085中文资料3A、29V 线性稳压器数据手册TI规格书

描述 Description

The LM1085 is a regulator with a maximum dropout of 1.5 V at 3 A of load current. It has the same pin-out as TI’s industry standard LM317.

Two resistors are required to set the output voltage of the adjustable output voltage version of the LM1085. Fixed output voltage versions integrate the adjust resistors.

The LM1085 circuit includes a zener trimmed bandgap reference, current limiting and thermal shutdown.

Refer to the LM1084 for the 5A version, and the LM1086 for the 1.5A version.

特性 Features

• Available in 3.3-V, 5.0-V, 12-V and Adjustable Versions
• Current Limiting and Thermal Protection
• Output Current 3 A
• Line Regulation 0.015% (typical)
• Load Regulation 0.1% (typical)

简介

LM1085属于集成电路（IC）的线性+开关稳压器。由TI制造生产的LM1085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。
