The device requires only one external resistor to set the output current, with 1% initial accuracy at the SET pin. As a true two-terminal device, it can be used as either a high-side or low-side current source without any ground reference. The device features reverse-battery protection, current limiting, and thermal shutdown, eliminating the need for external protection diodes in most applications.","working_principle":"The LT3092EST#PBF operates as a precision two-terminal current source using an internal 10uA reference current. **Current Setting**: An internal precision 10uA current flows out of the SET pin through an external resistor RSET. The voltage developed across RSET is buffered and applied to the output, forcing the same 10uA x RSET voltage across an internal 10 Ohm sense resistor, which sets the output current to IOUT = 10uA x RSET \/ 10 Ohm. **Two-Terminal Operation**: The device operates between its IN and OUT terminals. Current flows from IN through the internal pass transistor and sense resistor to OUT. The minimum operating voltage is 1.2V (IN to OUT), and the device can withstand up to 40V. **Protection Subsystem**: Reverse-battery protection prevents damage when input polarity is reversed. Internal current limiting and thermal shutdown protect against fault conditions. The device requires no output capacitor for stability.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>OUT<\/td><td>Current source output terminal<\/td><\/tr><tr><td>2<\/td><td>IN<\/td><td>Input supply terminal (1.2V to 40V)<\/td><\/tr><tr><td>3<\/td><td>SET<\/td><td>Current set pin (connect RSET to OUT)<\/td><\/tr><tr><td>Tab<\/td><td>OUT<\/td><td>Thermal tab, electrically connected to OUT<\/td><\/tr><\/table>","application_scenarios":"<ul><li>LED Biasing: Precision constant-current drive for high-power LEDs in lighting and display applications<\/li><li>4-20mA Loops: Industrial current-loop transmitters for sensor signal transmission<\/li><li>Battery Charging: Constant-current phase of Li-ion and NiMH battery chargers<\/li><li>Sensor Bias: Stable current excitation for resistive sensors (RTDs, strain gauges)<\/li><li>Intrinsic Safety: Current-limited circuits for hazardous environment equipment<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>LM334Z<\/td><td>TI<\/td><td>3-terminal, 1uA-10mA, TO-92<\/td><\/tr><tr><td>REF200AU<\/td><td>TI<\/td><td>Dual 100uA current source, SOIC-8<\/td><\/tr><tr><td>CRD2012-R10<\/td><td>TOSHIBA<\/td><td>Fixed 10mA, 2-terminal CRD<\/td><\/tr><tr><td>NSI45020T1G<\/td><td>onsemi<\/td><td>20mA, 45V, 2-terminal, SOD-123<\/td><\/tr><tr><td>AL5809-20P1-7<\/td><td>Diodes Inc<\/td><td>20mA, 50V, 2-terminal LED driver<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/6245","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=6245"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/6245\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=6245"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=6245"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=6245"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=6245"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
