In the SOT-223 package, it offers a compact surface-mount footprint with good thermal performance, making it ideal for modern PCB designs.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I set the output voltage on the LM317?\u003c\/h4\u003e\n\u003cp\u003eA: The output voltage of the LM317 is set using two external resistors connected between the adjustment pin, output pin, and ground. By choosing the right resistor values, you can dial in a precise output voltage between approximately 1.25V and 37V, depending on your input voltage.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these LM317 chips new and genuine?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. All 10 chips in this pack are in new, unused condition. They are rated at 40V input and 1.5A output and contain no high-concern chemicals, making them safe for professional and hobbyist electronics work.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the SOT-223 package suitable for through-hole or surface-mount PCBs?\u003c\/h4\u003e\n\u003cp\u003eA: The SOT-223 is a surface-mount (SMD) package. It is designed for use on surface-mount PCBs. If you need a through-hole version, look for the LM317 in TO-220 or similar packages instead.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the LM317 SOT-223 voltage regulator used for?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The LM317 is a popular adjustable three-terminal voltage regulator IC used in DC power supplies, battery chargers, LED drivers, and countless electronics projects.
