The output voltage is set by two external resistors: VOUT = 1.25V x (1 + R1\/R2) + IADJ x R1, where IADJ is typically 50uA (negligible for R1 < 1k). For 3.3V: R1=1.6k, R2=1k; for 5V: R1=3k, R2=1k. The dropout voltage is 1.1V at 800mA, meaning VIN must be at least 4.4V for 3.3V output at full load. The quiescent current is 5mA typical (10mA max), flowing from input to ground. The device requires a minimum 10uF output capacitor for stability; unlike older LDOs that required tantalum, the LM1117 is stable with ceramic capacitors of sufficient value (22uF X5R recommended). The ADJ pin also serves as the feedback node; a 10uF capacitor from ADJ to GND improves ripple rejection. The thermal shutdown activates at 155C, and current limiting is at 1.2A. The TO-252 package provides 3C\/W junction-to-tab, allowing 1.6W dissipation on a standard 1oz copper pour. The -DTX-ADJ suffix specifies TO-252, adjustable output. The LM1117 is one of the most widely used LDOs in the industry.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>ADJ\/GND<\/td><td>Input<\/td><td>Adjust pin (connect resistor divider from VOUT to set output: VOUT=1.25V x (1+R1\/R2))<\/td><\/tr><tr><td>2<\/td><td>VOUT<\/td><td>Output<\/td><td>Regulated output (800mA max, requires 10uF tantalum or ceramic for stability)<\/td><\/tr><tr><td>3<\/td><td>VIN<\/td><td>Input<\/td><td>Input supply (2.6-15V, must exceed VOUT + 1.1V)<\/td><\/tr><\/table>","application_scenarios":"<li>Industrial control<\/li><li>Consumer electronics<\/li><li>Communication equipment<\/li><li>Automotive electronics<\/li>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>Texas Instruments<\/td><td>LM1117DTX-ADJ\/NOPB<\/td><td>TO-252<\/td><td>Same device, TI brand<\/td><\/tr><tr><td>Texas Instruments<\/td><td>LM1117DT-3.3\/NOPB<\/td><td>TO-252<\/td><td>3.3V fixed version<\/td><\/tr><tr><td>onsemi<\/td><td>NCP1117DTADJG<\/td><td>TO-252<\/td><td>1A adjustable LDO, onsemi brand<\/td><\/tr><tr><td>Diodes Inc<\/td><td>AZ1117IH-ADJTRG1<\/td><td>SOT-223<\/td><td>1A adjustable LDO, Diodes Inc<\/td><\/tr><tr><td>Infineon<\/td><td>TLE4274G<\/td><td>TO-252<\/td><td>5V 40mA automotive LDO, Infineon<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/5605","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=5605"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/5605\/revisions"}],"predecessor-version":[{"id":6188,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/5605\/revisions\/6188"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=5605"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=5605"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=5605"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=5605"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
