JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD. 1.5A Adjustable Three-terminal Positive Voltage Regulator LM317 1 Adjustable Three-Terminal Regulator Introduction The LM317 is a three terminal positive voltage regulator with maximum 1.5A current output and adjustable output. The voltage regulator is very easy to use, which only needs two external resistors to set the output voltage, and the output voltage can be set in the range of 1.25V to 37V. In addition, the LM317 is also designed to integrate internal current limiting, thermal shutdown and safe working area compensation, which makes it relatively difficult to damage and basically prevent the burning of circuit fuses. The LM317 serves a variety of applications, including local voltage stabilization and card voltage stabilization. It can also be used to make a programmable voltage regulator, or as a precision current regulator by connecting a fixed resistance between the adjustment point and the output. 2 Applications • Air Conditioner Base Station Desktop Computer Digital Sign Ethernet Switch • • • • • • • • • • • • • NOT RECOMMENDED FOR NEW DESIGN, USE LM317C 3 Features • • The output current exceeds 1.5A The output is adjustable from 1.25V to 37V Internal thermal overload protection Temperature independent internal short circuit current limit Output transistor safe working area compensation Commonly used TO-252 package, as well as other forms of three pin package Avoid preparing multiple fixed voltages 4 Available Packages • • • • • PART NUMBER PACKAGE SOT-223 TO-220-3L LM317 TO-252-2L TO-263-2L IP Telephone: Wired and Wireless Motor Control Power Quality Meter Private Switch (PBX) Public Server Refrigerator Security Camera Signal or Waveform Generator Substation Control Washing Machine VIN IN LM317 IADJ ADJ VOUT OUT R1 COUT CIN 0.1µF 1.0µF R2 Typical Application Circuits Please carefully read the notice at the end of this data sheet about product use, data sheet changes and important statements. www.jscj-elec.com www.jscj-elec.com 11 Rev. .- -3.5 Rev 3.6  PDF
