LM317MDT集成电路（IC）的线性+开关稳压器规格书PDF中文资料

LM317MDT属于集成电路（IC）的线性+开关稳压器。由意法半导体集团制造生产的LM317MDT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。

DESCRIPTION

The LM217M/LM317M are monolithic integrated circuits in TO-220, DPAK, SOT-82 and SOT-194 packages intended for use as positive adjustable voltage regulators.

They are designed to supply until 500 mA of load current with an output voltage adjustable over a 1.2 to 37V range.

The nominal output voltage is selected by means of only a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.
