It's a 3-terminal 1A positive voltage regulator that outputs a fixed, regulated 12V DC from a higher unregulated DC input.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eLike all 78xx-family regulators, it requires no external components for basic operation — just input voltage and ground connections yield a stable, regulated 12V output. It includes built-in current limiting and thermal (over-temperature) shutdown protection, making it a robust, drop-in solution for powering downstream circuitry that needs a clean, fixed 12V rail.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eKey Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eType: 3-Terminal Fixed Positive Linear Voltage Regulator\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eManufacturer: AUK Corp (Kodenshi AUK Group)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePackage Marking: AUK \/ SN7812B\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePackage: TO-220F, isolated, 3-pin (Input, Ground, Output), through-hole\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOutput Voltage: 12V (fixed)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOutput Current: 1A (typical for this series; some variants rated up to 1.5A)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eInput Voltage Range: ~14.5V to 27–35V DC (typical for 78xx family)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eProtection: Built-in current limiting, thermal overload (over-temperature) shutdown\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eCommon Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGeneral-purpose fixed 12V power supplies\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRegulated rails for op-amp circuits, audio amplifiers, and sensor interfaces\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePost-regulation stage after AC-DC rectification in linear power supplies\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eArcade, industrial, and consumer electronics repair\/replacement (drop-in compatible with LM7812, MC7812, UA7812, and similar 78xx-family parts)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003ePackage Includes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e1 x AUK SN7812B 12V Voltage Regulator (TO-220F)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"digilog.pk","offers":[{"title":"Default Title","offer_id":51670482157846,"sku":null,"price":0.0,"currency_code":"PKR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/0764\/1366\/files\/SN7812B12VTO220F3Terminal1APositiveVoltageRegulator.jpg?v=1786188707","url":"https:\/\/digilog.pk\/products\/sn7812b-12v-to-220f3-terminal-1a-positive-voltage-regulator","provider":"digilog.pk","version":"1.0","type":"link"}
