This big chunky regulator will help you get your 7-35V battery or wall adapter down to a nice clean 5.0V with 2% regulation. Perfect for just about all electronics! This is the TO-220 version, with up to 1.5A current capability, and has internal current limiting + thermal shut-down protection which makes it sturdy and pretty much indestructible - at least electronics-wise (we're pretty sure a hammer might work...)\u003c\/p\u003e\n\u003cp\u003e This regulator has a ~2V linear drop-out. That means you must give it at \u003cem\u003eleast\u003c\/em\u003e 7V to get a clean 5V out. There is a constant 'quiescent' current draw of 6mA.\u003c\/p\u003e \u003cp\u003eThis regulator can provide up to 1.5A as long as it has proper heat-sinking. The higher your input voltage and output current, the more heat it will generate. Without an extra heatsink, you can burn off up to 2W. \u003ca href=\"http:\/\/www.daycounter.com\/Calculators\/Heat-Sink-Temperature-Calculator.phtml\"\u003eWe like this calculator for determining your heat sink requirements\u003c\/a\u003e It's a TO-220 package, so use 62.5°C\/Watt junction thermal resistance. The wattage of your set up is = (InputVoltage - 5V) * AverageCurrentInAmps. Eg a 9V battery and 1 Amp of average output current mean the regulator is burning off (9 - 5)*1 = 4 Watts! \u003ca href=\"https:\/\/www.adafruit.com\/products\/977\"\u003eThis setup would definitely need a heat sink!\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e This regulator does not require capacitors for stability, \u003ca href=\"https:\/\/www.adafruit.com\/product\/2195\"\u003ebut we recommend at least 10uF electrolytic capacitors on both input and output.\u003c\/a\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"video-insert\" alt=\"https:\/\/www.youtube.com\/embed\/ouhHKlIrG-I\" contenteditable=\"false\" allowfullscreen=\"true\" frameborder=\"0\" src=\"https:\/\/img.youtube.com\/vi\/ouhHKlIrG-I\/hqdefault.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"video-insert\" alt=\"https:\/\/www.youtube.com\/embed\/vxDZktaVE_M?start=566\" contenteditable=\"false\" allowfullscreen=\"true\" frameborder=\"0\" src=\"https:\/\/img.youtube.com\/vi\/vxDZktaVE_M\/hqdefault.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"video-insert\" alt=\"https:\/\/www.youtube.com\/embed\/rUuwO3Q8N6o?start=566\" contenteditable=\"false\" allowfullscreen=\"true\" frameborder=\"0\" src=\"https:\/\/img.youtube.com\/vi\/rUuwO3Q8N6o\/hqdefault.jpg\"\u003e\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"4-6 Days","offer_id":47700413088089,"sku":"ADA-2164\/B","price":1.1,"currency_code":"EUR","in_stock":true},{"title":"1 day","offer_id":47886543651161,"sku":"ADA-2164\/A","price":1.1,"currency_code":"EUR","in_stock":false},{"title":"2-4 Weeks","offer_id":47886710145369,"sku":"ADA-2164","price":1.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/1009\/7753\/files\/2164-01.jpg?v=1705519286","url":"https:\/\/robot-italy.com\/en\/products\/2164-5v-1-5a-linear-voltage-regulator-7805-to-220","provider":"Robot Italy","version":"1.0","type":"link"}
