LM317M中文资料中等电流1.2至37 V可调稳压器数据手册ST规格书

描述 Description

The LM217M and LM317M are monolithic integrated circuits in DPAK and SOT223 packages used 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 37 V range. The nominal output voltage is selected by one resistive divider only, making the device exceptionally easy to configure and avoiding the use of several fixed regulators.

特性 Features

• Output voltage range: 1.2 to 37 V
• Output current in excess of 500 mA
• Line regulation typ. 0.01%
• Load regulation typ. 0.1%
• Thermal overload protection
• Short-circuit protection
• Output transition safe area compensation
• Floating operation for high voltage applications

简介

LM317M属于集成电路（IC）的稳压器-线性。由制造生产的LM317M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。
