LM317T集成电路（IC）的稳压器-线性规格书PDF中文资料

LM317T属于集成电路（IC）的稳压器-线性。由意法半导体集团制造生产的LM317T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。

The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP 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. The nominal output voltage is selected by means of a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.

1. Output voltage range: 1.2 to 37 V

2. Output current in excess of 1.5 A

3. 0.1 line and load regulation

4. Floating operation for high voltages

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