Features ultra-low 0.2 Ohm dynamic impedance, 400uA to 10mA operating current, and adjustable temperature coefficient via the ADJ pin. The 2.49V output is convenient for obtaining a stable reference from 5V logic supplies. MX suffix denotes SOIC-8 tape-and-reel. Ideal for 8-bit ADC\/DAC references and digital voltmeters.","working_principle":"The LM336-2.5 uses a bandgap reference circuit to generate a stable 2.49V shunt voltage. The 0.2 Ohm dynamic impedance is significantly better than conventional Zener diodes, providing excellent load regulation. The ADJ pin connects to the internal bandgap node and can be used with external resistors to trim both the output voltage and minimize the temperature coefficient. When adjusted to exactly 2.49V using a potentiometer and series diodes, the temperature coefficient can approach zero, making it ideal for precision applications.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>ADJ<\/td><td>Input<\/td><td>Adjust terminal (for voltage\/tempco trimming)<\/td><\/tr><tr><td>2<\/td><td>V+<\/td><td>Output<\/td><td>Positive terminal (cathode)<\/td><\/tr><tr><td>3<\/td><td>V-<\/td><td>Ground<\/td><td>Negative terminal (anode)<\/td><\/tr><tr><td>4-8<\/td><td>NC<\/td><td>-<\/td><td>No connect<\/td><\/tr><\/table>","application_scenarios":"<ul><li>2.5V ADC reference for 8-bit data acquisition from 5V supply<\/li><li>Digital voltmeter half-scale reference<\/li><li>4-20mA current loop measurement reference<\/li><li>Precision comparator threshold reference<\/li><li>Battery-powered instrumentation reference<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>LM336Z-2.5\/NOPB<\/td><td>TO-92<\/td><td>TO-92 through-hole version<\/td><\/tr><tr><td>ADI<\/td><td>LT1009CZ<\/td><td>TO-92<\/td><td>+\/-5% 2.5V reference<\/td><\/tr><tr><td>TI<\/td><td>TL431AIACT<\/td><td>SOT-23-3<\/td><td>Programmable shunt, smaller package<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3366","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=3366"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/3366\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=3366"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=3366"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=3366"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=3366"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
