It has a wide operating input voltage range of 13.2 to 450V. The output voltage can be adjusted from 1.2 to 440V provided that the input voltage is at least 12V greater than the output voltage. The output voltage can be adjusted by means of two external resistors R1 and R2 as shown in the typical application circuits. The LR8 regulates the voltage difference between VOUT and ADJ pins to a nominal value of 1.2V. The 1.20V is amplified by the external resistor ratio R1 and R2. An internal constant bias current of typically 10µA is connected to the ADJ pin. This increases VOUT by a constant voltage of 10µA times R2. The LR8 has current limiting and temperature limiting. The output current limit is typically 20mA and the minimum temperature limit is 125°C. An output short circuit current will therefore be limited to 20mA.\u003c\/div\u003e\n\u003cdiv id=\"fnb_features\" class=\"featuresList\"\u003e\n\u003cul class=\"firstList\"\u003e\n\u003cli\u003e13.2 to 450V Input voltage range\u003c\/li\u003e\n\u003cli\u003e5% Output voltage tolerance\u003c\/li\u003e\n\u003cli\u003eOutput current limiting\u003c\/li\u003e\n\u003cli\u003e10µA Typical ADJ current\u003c\/li\u003e\n\u003cli\u003eInternal junction temperature limiting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"pdpApplication\"\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp class=\"pdpApplicationList\"\u003eIndustrial, Motor Drive \u0026amp; Control, Power Management\u003c\/p\u003e\n\u003ctable class=\"details-table-desktop\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eCountry of Origin:\u003c\/th\u003e\n\u003ctd\u003eUnited States\n\u003cp\u003eCountry in which last significant manufacturing process was carried out\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eHSN No:\u003c\/strong\u003e\u003c\/th\u003e\n\u003ctd\u003e85423100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch4 data-mce-fragment=\"1\"\u003e\u003c\/h4\u003e\n\u003ch4 data-mce-fragment=\"1\"\u003eOther details\u003c\/h4\u003e\n\u003ctable data-mce-fragment=\"1\"\u003e\n\u003ctbody data-mce-fragment=\"1\"\u003e\n\u003ctr data-mce-fragment=\"1\"\u003e\n\u003ctd data-mce-fragment=\"1\"\u003eBrand\u003c\/td\u003e\n\u003ctd data-mce-fragment=\"1\"\u003eMicrochip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr data-mce-fragment=\"1\"\u003e\n\u003ctd data-mce-fragment=\"1\"\u003ePart Number\u003c\/td\u003e\n\u003ctd data-mce-fragment=\"1\"\u003eLR8K4-G\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr data-mce-fragment=\"1\"\u003e\n\u003ctd data-mce-fragment=\"1\"\u003eQuantity\u003c\/td\u003e\n\u003ctd data-mce-fragment=\"1\"\u003eEach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr data-mce-fragment=\"1\"\u003e\n\u003ctd data-mce-fragment=\"1\"\u003eTechnical Data Sheet EN\u003c\/td\u003e\n\u003ctd data-mce-fragment=\"1\"\u003e\u003ca href=\"https:\/\/www.farnell.com\/datasheets\/2138212.pdf\" title=\"Download data sheet MICROCHIP LR8K4-G Linear Voltage Regulator, Adjustable, 1.2V to 440V\/20 mA out, TO-252AA-3\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/files\/file_4379f50c-e237-48f9-beae-a4e625c5b304_icon.png?9736775303194905289\" alt=\"Download technical document - datasheet - Tanotis India\" width=\"25\" data-mce-fragment=\"1\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/files\/file_4379f50c-e237-48f9-beae-a4e625c5b304_icon.png?9736775303194905289\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
