It features a metal tab that can be bolted to a heatsink for efficient heat dissipation, making it ideal for linear voltage regulator circuits that may generate heat under load. Its standardized pin layout ensures compatibility with the vast majority of PCBs and breadboard setups.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use these voltage regulators with Arduino or Raspberry Pi projects?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The L7805CV (5V) and LM317T are especially popular for powering Arduino boards, sensors, and other 5V logic circuits from higher-voltage supplies. The full range of regulators in this kit gives you flexibility for projects requiring 5V, 9V, 12V, or other standard voltages.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these ICs new or used?\u003c\/h4\u003e\n\u003cp\u003eA: All components in this kit are brand new and in unused condition, sourced directly from manufacturing stock.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What voltage regulators are included in this 50PCS TO-220 kit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The kit includes the LM317T adjustable voltage regulator and nine fixed positive voltage regulators from the L78xx series: L7805CV (5V), L7806CV (6V), L7808CV (8V), L7809CV (9V), L7810CV (10V), L7812CV (12V), L7815CV (15V), L7818CV (18V), and L7824CV (24V) — 50 pieces in total across all models.\"}}, {\"@type\": \"Question\", \"name\": \"What is the TO-220 package and why does it matter?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The TO-220 is a widely used through-hole transistor and IC package.
