Description

The LM117, LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP, TO-3 and D²PAK packages intended for use as positive adjustable voltage regulators.

They are designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 to 37 V range.

Features

■ Output voltage range: 1.2 to 37 V

■ Output current in excess of 1.5 A

■ 0.1 Line and load regulation

■ Floating operation for high voltages

■ Complete series of protections: current limiting, thermal shutdown and SOA control

LM217D2T-TR属于集成电路（IC） > 线性 + 开关稳压器。意法半导体（ST）集团制造生产的LM217D2T-TR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。
