描述 Description

The LM337 is an adjustable 3-terminal negative linear voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of -1.2V to -37 V. This linear voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. Further, it employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow-out proof. The LM337 serves a wide variety of applications including local, on card regulation. This linear voltage regulator can also be used to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM337 can be used as a precision current regulator.

特性 Features

• Output Current in Excess of 1.5 A
• Output Adjustable between -1.2 V and -37 V
• Internal Thermal Overload Protection
• Internal Short Circuit Current Limiting Constant with Temperature
• Output Transistor Safe-Area Compensation
• Floating Operation for High Voltage Applications
• Eliminates Stocking many Fixed Voltages
• Available in Surface Mount D2PAK and Standard 3-Lead Transistor Package
• Pb-Free Packages are Available

简介

LM337属于集成电路(IC)的稳压器-线性。由制造生产的LM337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。
