The available output current is a function of the input voltage, output voltage, and efficiency (see \u003cem\u003eTypical Efficiency and Output Current\u003c\/em\u003e section below), but the input current can typically be as high as 1.2 A.\u003c\/p\u003e\n\u003cp\u003eThe regulator’s thermal shutdown engages at around 140°C and helps prevent damage from overheating, but it does \u003cstrong\u003enot\u003c\/strong\u003e have reverse-voltage protection.\u003c\/p\u003e\n\u003ctable class=\"picture_with_caption right\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003ca class=\"noscript-fallback\" href=\"https:\/\/a.pololu-files.com\/picture\/0J4683.1200.jpg?370d00edaf77a210b4ab4f08804a3953\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\u003cimg class=\"zoomable\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/0J4683_250.jpg\" alt=\"\" data-gallery-pictures='\u0026lt;{\"id\":\"0J4683\",\"caption\":\"\\u003cp\\u003ePololu step-up voltage regulator U1V10F3\/U1V10F5 in a breadboard.\\u003c\/p\\u003e\",\"url_tiny\":\"https:\/\/a.pololu-files.com\/picture\/0J4683.98x98.jpg?370d00edaf77a210b4ab4f08804a3953\",\"url_medium\":\"https:\/\/a.pololu-files.com\/picture\/0J4683.600x480.jpg?370d00edaf77a210b4ab4f08804a3953\",\"url_full\":\"https:\/\/a.pololu-files.com\/picture\/0J4683.1200.jpg?370d00edaf77a210b4ab4f08804a3953\",\"longest_side\":800}\u0026gt;' data-picture-id=\"0J4683\" data-picture-longest_side=\"800\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInput voltage: 0.5 V to 5.5 V\u003c\/li\u003e\n\u003cli\u003eFixed 5 V output with 4% accuracy\u003c\/li\u003e\n\u003cli\u003eAutomatic linear down-regulation when the input voltage is greater than the output voltage\u003c\/li\u003e\n\u003cli\u003e1.2 A switch allows for input currents up to 1.2 A\u003c\/li\u003e\n\u003cli\u003eGood efficiency at light load: \u0026lt;1 mA typical no-load quiescent current, though it can exceed 1 mA for very low input voltages\u003c\/li\u003e\n\u003cli\u003eIntegrated over-temperature shutoff\u003c\/li\u003e\n\u003cli\u003eSmall size: 0.35? ?0.45?; ?0.1?

However, once the regulator is on, the input voltage can drop as low as 0.3 V and the 5 V output voltage will be maintained on VOUT. Unlike standard boost regulators, this regulator has an additional linear down-regulation mode that allows it to convert input voltages as high as 5.5 V down to 5 V for small to moderate sized loads. When the input voltage exceeds 5 V, the regulator automatically switches to this down-regulation mode. The input voltage should not exceed 5.5 V. Please be wary of destructive LC spikes that might cause the input voltage to surpass 5.5 V (see below for more information).\u003c\/p\u003e\n\u003cp\u003eThe three connections are labeled on the back side of the PCB, and they are arranged with a 0.1? spacing along the edge of the board for compatibility with solderless breadboards, connectors, and other prototyping arrangements that use a 0.1? grid.
