The design is based on the well-known LM317-M circuit, with the addition of a 12-bit DAC, 12-bit ADC, and an Operational Amplifier. Two pairs of screw terminals serve as inputs and outputs.\u003c\/p\u003e \u003cp\u003eThe LM317-M IC is a reliable regulator with typical line regulation of 0.01% and load regulation of 0.1%. It also has internal short-circuit current limiting and thermal overload protection.\u003c\/p\u003e \u003cp\u003eThe circuit regulates voltage by turning all input\/output difference into heat (effectively dissipating all the excess power). If it gets too hot it may damage the board or cause unexpected behaviour.\u003c\/p\u003e \u003cp\u003eBecause of that, the board�s operating range is defined by two factors. 1) maximum input voltage and current (should not exceed 20V\/0.5A); and 2) maximum wattage arising from current and I\/O voltage difference (should not exceed 1W, measured as I x (Input V - Output V).\u003c\/p\u003e \u003cp\u003eThe board also carries a MOSFET chip to toggle the output on and off.\u003c\/p\u003e \u003cp\u003eVReg Click communicates with the target board MCU through the SPI interface (CS, SCK, MISO, MOSI). The board can use either a 3.3V or a 5V power supply.\u003c\/p\u003e \u003cp\u003eIt is also possible to use the board�s power supply as the Input, by resoldering the onboard INPUT SEL jumper.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInterface: SPI\u003c\/li\u003e \u003cli\u003eCompatibility: mikroBUS�\u003c\/li\u003e \u003cli\u003eDimensions: 57.15 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V or 5V\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/d\/5\/f\/c\/f\/Schematic-18898-VReg_Click.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/a\/2\/d\/2\/f\/LM317M_datasheet.pdf\"\u003eLM317M Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/MikroElektronika\/mikrosdk_click_v2\/tree\/master\/clicks\/vreg\"\u003eGitHub\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eVideos\u003c\/strong\u003e\u003c\/p\u003e \u003cdiv class=\"flex-video-wrap clearfix\"\u003e \u003cdiv class=\"flex-video widescreen img\"\u003e \u003ciframe src=\"https:\/\/www.youtube.com\/embed\/zzlh1oGii1Q\/?autohide=1\u0026amp;border=0\u0026amp;wmode=opaque\u0026amp;enablejsapi=1\" frameborder=\"0\" allowfullscreen width=\"560\" height=\"315\"\u003e\u003c\/iframe\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40054686941269,"sku":"18898:PRT-18898:spark","price":4150.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/18898_-_VReg_Click.jpg?v=1651342265","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-vreg-click","provider":"Tanotis","version":"1.0","type":"link"}
