The higher pack quantity options are cheaper per item. If you would like to mix the available types in a pack, please use the MIX option and send me a list of your requirements in a site message, or attach a note to the purchase. Some of the items are rated for 1.5 Amps.\u003c\/p\u003e\n\u003cp\u003e7805 = 5V output\u003cbr\u003e7812 = 12V\u003cbr\u003e7910 = -10V output etc\u003c\/p\u003e\n\u003cp\u003eIf you are replacing a part there may be various suffixes like 78L12AC for the voltage tolerance and temperature range. These are not generally of paramount importance in most consumer equipment. A \"G\" suffix on On semi parts shows RoHs compliance.\u003c\/p\u003e\n\u003cp\u003eThere are also various prefixes from various manufacturers like \"MC\" for On Semiconductor, \"LM\" for National Semiconductor, \"L\" for ST etc which are generally unimportant. On Semiconductor is the company that took over the Motorola portfolio. All of the fixed voltages available can be found on this listing.\u003c\/p\u003e\n\u003cp\u003eAlso available are the LM317 positive adjustable regulator and the LM337 negative voltage regulator. On these items the output voltage is set by a pair of resistors. There is an LM7805C made by Fairchild, as people do seem to like this specific type for some reason.\u003c\/p\u003e\n\u003cp\u003eThe +10V types are sometimes found in older automotive electronics sitting somewhere behind the dashboard to stabilise the supply voltages on the instruments. My old Mini 1275GT had one. In these cases the regulator here will do the job electrically but the pin-out is likely to be different, so some pin-bending adaptation will be required. The +8V version is often seen powering the RF receiver sections in CB radios. Again, these parts will do the job electrically but the pin-out will be different. The metal tabs are internally connected to pin 2, so the tab may require isolation with a mica shim and insulating washer if bolted to a chassis for heat dissipation.\u003c\/p\u003e\n\u003cp\u003eSome high voltage input AVHT and low dropout types are available on another listing in my Etsy shop.\u003c\/p\u003e\n\u003cp\u003eAvailable Items:\u003c\/p\u003e\n\u003cp\u003eType Number Output Voltage Manufacturer\u003c\/p\u003e\n\u003cp\u003eLM317T Positive Adjustable On Semi\u003cbr\u003eMC7824CT +24V On Semi\u003cbr\u003eMC7818CT +18V On Semi\u003cbr\u003eMC7815CT +15V On Semi\u003cbr\u003eMC7812CT +12V On Semi\u003cbr\u003eL7810CV +10V ST\u003cbr\u003eMC7809CT +9V On Semi\u003cbr\u003eMC7808CT +8V On Semi\u003cbr\u003eMC7806CT +6V On Semi\u003cbr\u003eMC7805CT +5V On Semi\u003cbr\u003eLM7805C +5V Fairchild\u003cbr\u003eMC7905ACT -5V On Semi\u003cbr\u003eMC7906CT -6V On Semi\u003cbr\u003eL7908CV -8V ST\u003cbr\u003eLM7909C -9V Fairchild\u003cbr\u003eLM7910C -10V Fairchild\u003cbr\u003eMC7912CT -12V On Semi\u003cbr\u003eMC7915ACT -15V On Semi\u003cbr\u003eMC7918CT -18V On Semi\u003cbr\u003eTS7924 -24V Taiwan Semiconductor\u003cbr\u003eLM337T Negative Adjustable On Semi\u003c\/p\u003e","brand":"HJW Electronics","offers":[{"title":"LM317T +ADJ","offer_id":58814392435072,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7824CT +24V","offer_id":58814392467840,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7818CT +18V","offer_id":58814392500608,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7815CT +15V","offer_id":58814392533376,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7812CT +12V","offer_id":58814392566144,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"L7810CV +10V","offer_id":58814392598912,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7809CT +9V","offer_id":58814392631680,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7808CT +8V","offer_id":58814392664448,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7806CT +6V","offer_id":58814392697216,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7805CT +5V","offer_id":58814392729984,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"LM7805C +5V","offer_id":58814392762752,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7905ACT -5V","offer_id":58814392795520,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7906CT -6V","offer_id":58814392828288,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"L7908CV -8V","offer_id":58814392861056,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"LM7909C -9V","offer_id":58814392893824,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"LM7910C -10V","offer_id":58814392926592,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7912CT -12V","offer_id":58814392959360,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7915ACT -15V","offer_id":58814392992128,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"MC7918CT -18V","offer_id":58814393024896,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"TS7924 -24V","offer_id":58814393057664,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true},{"title":"LM337T -ADJ","offer_id":58814393090432,"sku":null,"price":1.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2136\/1280\/files\/group_top.jpg?v=1788110740","url":"https:\/\/shop.usefulcomponents.com\/products\/linear-voltage-regulator-ic-three-terminal-to-220-negative-and-positive","provider":"HJW Electronics","version":"1.0","type":"link"}
