The device requires only two external resistors to set the output voltage. The device features a typical line regulation of 0.01% and typical load regulation of 0. 1% . The LM317 includes current limiting, thermal overload protection, and safe operating area protection. Overload protection remains functional even if the ADJUST pin is disconnected.  \nTypically, no capacitors are needed unless the device is situated more than 6 inches from the input filter capacitors. In that case, an input bypass is needed. Add an optional output capacitor to improve transient response. Bypass the adjustment pin to achieve very high ripple rejection ratios that are difficult to achieve with standard 3-pin regulators.  \nPackage Information  \n\n| PART NUMBER | PACKAGE(1) | PACKAGE SIZE(2) |\n| --- | --- | --- |\n| LM317 | DCY (SOT-223, 4) | 6.5mm × 7mm |\n|  | KTT (TO-263, 3) | 10. 16mm × 15.24mm |\n|  | KCS, KCT (TO-220, 3)(3) | 10. 16mm × 4.55mm |\n\n(1) For more information, see the Mechanical, Packaging, and Orderable Information.  \n(2) The package size (length × width) is a nominal value and includes pins, where applicable.  \n(3) Legacy chip.  \nVI  \nBattery-Charger Circuit  \nAn IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers. PRODUCTION DATA.  \nThe regulator is floating and detects only the input-to-output differential voltage. Thus, supplies of several hundred volts are regulated as long as the maximum input-to-output differential is not exceeded. That is, avoid short-circuiting the output.  \nBy connecting a fixed resistor between the adjustment pin and output, the LM317 is also able to be used as a precision current regulator. Supplies with electronic shutdown are achieved by clamping the adjustment terminal to ground, which programs the output to 1.25V where most loads draw little current.  \n2 Submit Document Feedback Copyright © 2025 Texas Instruments Incorporated Product Folder Links: LM317  \nTable of Contents  \n1 Features............................................................................ 1  \n2 Applications..................................................................... 1  \n3 Description....................................................................... 1  \n4 Device Comparison Table...............................................4  \n5 Pin Configuration and Functions...................................5  \n6 Specifications.................................................................. 6  \n6.1 Absolute Maximum Ratings........................................ 6  \n6.2 ESD Ratings............................................................... 6  \n6.3 Recommended Operating Conditions.........................6  \n6.4 Thermal Information (Legacy Chip) ............................ 7  \n6.5 Thermal Information (New Chip) ................................. 7  \n6.6 ","cbCaioJ0iBnZEed0","https://ap.wps.com/l/cbCaioJ0iBnZEed0","pdf",2578150,45,"English","# 1 Features\n# 2 Applications\n# 3 Description\n# 4 Device Comparison Table\n# 5 Pin Configuration and Functions\n# 6 Specifications\n## 6.1 Absolute Maximum Ratings\n## 6.2 ESD Ratings\n## 6.3 Recommended Operating Conditions\n## 6.4 Thermal Information (Legacy Chip)\n## 6.5 Thermal Information (New Chip)\n## 6.6 Electrical Characteristics\n## 6.7 Typical Characteristics\n# 7 Detailed Description\n## 7.1 Overview\n## 7.2 Functional Block Diagram\n## 7.3 Feature Description\n## 7.4 Device Functional Modes\n# 8 Application and Implementation\n## 8.1 Application Information\n## 8.2 Typical Application\n## 8.3 System Examples\n## 8.4 Power Supply Recommendations\n## 8.5 Layout\n# 9 Device and Documentation Support\n# 10 Revision History\n# 11 Mechanical, Packaging, and Orderable Information","[{\"question\":\"What output voltage and current ranges does the LM317 support?\",\"answer\":\"The LM317 provides an adjustable output voltage range of 1.25V to 37V and supports an output current of 1.5A.\"},{\"question\":\"How is the LM317 output voltage set?\",\"answer\":\"The output voltage is set using two external resistors.\"},{\"question\":\"What protection features are built into the LM317?\",\"answer\":\"The LM317 includes current limiting, thermal overload protection, and safe operating area protection, with overload protection remaining functional even if the ADJUST pin is disconnected.\"}]","LM317 - 3-Pin Adjustable Regulator | PDF",113]
