LT1003数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

OBSOLETE: For Information Purposes Only. Contact Analog Devices for Potential Replacement.

The LT1003 is a 5 amp version of the popular LM123 5V regulator. In addition to higher output current, it offers improved line regulation and an initial output voltage tolerance of ±2%. These tightened specifications ease design and application problems several ways: safety margin is improved, error budgets on other parts of the system are expanded, and output voltage loss due to long supply runs can be better tolerated.

The LT1003 incorporates LTC's advanced design, process and test techniques for improved quality and reliability over similar device types. Specifically, all devices are burned in by shorting the outputs, thereby forcing the regulator into its current limit and eventually, thermal limit mode. This ensures that all device protection features are working.

简介

LT1003属于集成电路（IC）的线性+开关稳压器。由制造生产的LT1003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。
